What is Endpoint Protection?

Endpoint protection is security that monitors and protects against various cyber threats. It protects endpoints like laptops, desktops, smartphones, tablets, PCs, and other devices. Endpoint protection involves using an endpoint protection platform that is deployed on endpoint devices to prevent malware and file-based malicious processes; endpoint protection also responds to dynamic security incidents and threats. It includes threat investigation, remediation, and uses multiple detection techniques ranging from static to behavioral analysis.

Endpoint protection security guards devices and acts as a shield for the whole network. This layered approach uses different technologies and methods to stop, spot, and mitigate threats:

• Prevention: It uses application whitelisting, device control, and advanced anti-malware to stop known and unknown threats from running.
• Detection: The best endpoint protection will use a mix of behavior analysis and machine learning to spot suspicious activities that might signal a breach attempt.
• Response: It offers automatic incident response tools, such as isolating infected endpoints, stopping harmful processes, and undoing changes made by threats.

Endpoint protection features limit entry points; they reduce the chance of attackers using compromised devices to launch larger network attacks. Top endpoint protection software can increase the scope of security coverage as well.

Why is Endpoint Protection Important?

Businesses use endpoint security to keep all the devices connected to a network secure. They can detect suspicious activity and prevent risks by making endpoints the new network perimeter, no matter where employees are located.

Greater risk due to BYOD policies and remote work

According to Forbes, 12.7% of American workers now do their jobs remotely, while 28.2% choose a mix of remote and in-office work. This trend means more personal devices now connect to company networks, increasing the possible targets for cyber attacks.

Prevents lateral movement within networks

Once an attacker breaches an endpoint, they can move laterally across the network. They can spread their attacks to more endpoints and access valuable assets such as databases or sensitive customer information.

Endpoint security solutions prevent this by:

• Isolating infected devices: Endpoint protection can quarantine or isolate the infected endpoint to prevent the attacker from moving laterally.
• Zero trust architecture: Modern endpoint security systems operate under Zero Trust security principles. They assume no device or user is trustworthy by default. It requires continuous verification of all devices and users. Good zero trust endpoint protection limits the ability for attackers to move undetected.

Reduces dwell time of cyberattacks

Dwell time refers to the time gap between when a cyberattack enters the network and when it is detected and neutralized. The longer the dwell time, the more damage an attacker can do. This includes extracting data, installing backdoors, or compromising additional systems.

Advanced endpoint security significantly reduces dwell time by:

• Real-time monitoring: Constantly watching all endpoints for such activities, making detection near-instantaneous compared to manual or periodic scans.
• Automated response capabilities: When a threat is detected, modern endpoint security tools can automatically isolate the device, roll back changes, and alert administrators, drastically shortening the time from detection to containment.

Reducing dwell time is crucial for protecting high-value assets and ensuring business continuity. It applies especially when attackers use sophisticated methods to stay hidden for extended periods.

By investing in thorough endpoint protection, businesses can dodge such huge financial hits and keep their customers’ trust. This ensures that one compromised device does not cause widespread harm.

Benefits of Endpoint Protection

Endpoint protection in cybersecurity enhances the security posture of a business. It makes sure that all devices connected to the network are monitored and protected against unauthorized access. Cyber security endpoint protection offers the following benefits:

Centralized Management

It is impossible to manually manage hundreds of laptops and mobile devices connected to the network. Cybersecurity endpoint protection offers a centralized way to manage all these devices. This allows IT admins to monitor and update policies and ensure compliance with a single dashboard. Moreover, centralized management improves the visibility of the entire organization to identify and prevent threats.

Securing Remote Work

According to FlexJobs, 63% of employees want to work remotely on a salary.

This highlights the demand for remote work and raises the need to secure these remote devices properly. An advanced endpoint protection platform protects remote devices by offering multi-factor authentication, data encryption, mobile device management, robust antivirus/malware software, and network security. These features allow employees and organizations to work seamlessly and securely.

Uninterrupted Work and Productivity

Malware, phishing, and other cyber attacks disrupt the workflow and cause huge losses to the company. Organizations that use endpoint protection save approximately $2.2M and provide a safe environment for employees to work without interruptions. So, it cuts down costs and improves productivity and revenue.

Data Protection

Endpoint protection primarily employs two methods – Data Loss Prevention (DLP) and encryption. DLP refers to a set of processes that monitor, identify, and prevent sensitive information from being compromised from an organization’s network.

How it Works?

DLP identifies sensitive data by specific keywords or patterns, predefined labels, or associated tags. Then, it monitors the data to detect any attempts to access, copy, or transmit it. It blocks, quarantines, or alerts the admins when it detects a potential threat.

Encryption is the process of converting plain data into a coded format that prevents individuals from understanding them. It can encrypt the data at rest and in transit, protecting it in both stages.

By using the DLP and encryption, endpoint protection software lays a strong security foundation for your sensitive data and prevents data theft.

Types of Endpoint Protection

Apart from a firewall, antivirus, and EDR (which have been mentioned previously), here are a few types of endpoint protection:

1. Endpoint Protection Platform (EPP)

EPP in cybersecurity is a comprehensive solution that bundles all essential tools like antivirus, firewall, EDR, intrusion prevention systems, and application control into a single platform. It simplifies the management of multiple devices and enhances overall protection.

2. Endpoint Detection & Response (EDR)

EDR solutions will continuously monitor, detect, investigate and automate responses to threats. They can detect advanced and unknown threats, which are capable of bypassing traditional EPPs. EDR will use a mix of machine learning and behavioral analytics to find anomalies. And some of these solutions can even do forensic analysis for security teams.

3. Extended Detection & Response (XDR)

XDR is a cybersecurity framework that correlates data from various security tools like EPP, data loss prevention, and network security across the organization’s entire infrastructure.

XDR enables security teams to hunt for threats proactively. If it detects a threat during the hunt, it can automate certain responses, such as quarantining infected devices or blocking malicious traffic.

While EDR and XDR share some similarities, XDR differs in providing a broader scope and correlating data from multiple sources.

4. Managed Detection and Response (MDR)

Managed detection and response (MDR) services give you that extra layer of human expertise which is normally lacking in-house. MDR solutions will blend EDR or XDR and can be managed by third-party security operations center teams. They provide 24x7 threat hunting and incident response services.

5. Internet of things (IoT) protection 

IoT security includes devices that have software embedded into them and can exchange information with other devices over the internet. These devices include but are not limited to refrigerators, doorbells, smart bulbs, dash cams, and home security sensors.

These devices can be protected by regularly monitoring for suspicious activities, using secure communication protocols, such as HTTPS and TLS, and restricting who can access the IoT devices.

Endpoint Protection vs. Antivirus Software

Endpoint security protection and antivirus might seem similar at first glance, but they differ in scope, detection methods, additional features, and scalability. Let us explore each of them.

Scope: Antivirus focuses mainly on malware, while endpoint protection can protect from a broader range of threats, including network-level attacks, file-less malware, and advanced attacks like phishing and ransomware.

Detection methods: Antivirus is generally reliant on signature-based detection, whereas endpoint protection uses a combination of methods like behavior analysis, AI, and machine learning to detect even unknown or emerging threats.

Additional features: Endpoint protection platforms typically include advanced security features like firewalls, intrusion prevention systems, device control, and encryption, offering a more comprehensive defense than antivirus.

Scalability: Antivirus solutions are typically designed for individual devices or small businesses, focusing on basic protection. On the other hand, endpoint protection platforms are built to scale across large, complex networks. They safeguard multiple devices, on-site or remote while maintaining centralized management and consistent security policies across all endpoints.

Feature	Antivirus	Endpoint Protection
Network Security	Focuses on device-level protection with minimal network security features.	Integrates firewall, intrusion detection/prevention (IDS/IPS), and network traffic analysis to protect endpoints across a corporate network.
Device Management	Typically installed on individual devices with limited or no centralized management.	Centralized management console allows IT teams to manage, monitor, and secure all endpoints across the network, enabling policy enforcement and patch management.
Access Control and Identity Management	Limited or no access control features.	Offers multi-factor authentication (MFA), identity and access management (IAM), and user policy enforcement to prevent unauthorized access to corporate systems.

User Interface and Usability	Typically straightforward and user-friendly for individuals.	More complex but designed for IT administrators, offering detailed dashboards, reporting, and customizable security policies for managing multiple endpoints.

Key Components of Endpoint Protection

Endpoint protection platforms (EPPs) combine several advanced elements to build a strong layered defense system. Let us examine these crucial parts and how they work together to protect your digital assets.

1. Antivirus/anti-malware software

Antivirus/anti-malware software is at the heart of endpoint protection. It spots and gets rid of known viruses, worms, and ransomware. It also uses advanced methods to fight new threats.

A top-notch antivirus program has real-time scanning, which monitors files and processes as they are accessed or run. It also uses heuristic analysis, which employs pattern recognition to spot potential threats.

Many new solutions also use sandbox testing, which runs suspected files in a controlled setting to observe their actions. 

2. Firewall

A firewall monitors the traffic (coming in and going out) between your device and the Internet based on preset security rules.

It works as a shield, preventing unauthorized access and blocking harmful attempts to take advantage of vulnerabilities.

High-tech firewalls analyze data at the application layer, allowing more granular control over the network by inspecting the transmission data’s content, context, and behavior.

3. Intrusion detection/prevention system (IDS/IPS)

An intrusion detection system (IDS) keeps an eye on computer and network systems to spot fishy activity. Here, “fishy” might mean weird login patterns like multiple failed attempts, sudden surges in network traffic, attempting to break into secured data, known attack signs, odd systems, or user behavior.

An Intrusion Prevention System (IPS) takes things a step further. It spots break-ins using different methods. One way is signature-based detection, which matches network packets against a list of known attack patterns.

Another is anomaly-based detection, which sets up a normal behavior baseline and flags anything that does not fit. Protocol analysis looks for behavior that does not match what is expected from protocols.

Heuristic-based detection uses algorithms to identify possible threats based on past events. When an IPS spots a break-in, it can act on its own, like blocking traffic, resetting the connection, or alerting admins.

4. Device and application control

Device control limits the types of hardware that can connect to a network or endpoint. It allows you to restrict access to specific USB ports or approve hardware devices, stopping data theft through unauthorized external storage.

Application control, in contrast, manages which apps or programs can run on endpoints. This stops the installation of unapproved apps without prior approval, reducing the chance of harmful programs gaining a foothold in your system.

5. Behavioral analysis and machine learning

Behavioral analysis is a complex process that identifies unusual patterns, such as login attempts outside of normal working hours, or unauthorized access on endpoints. Machine learning algorithms boost this ability by spotting threats or oddities based on past data, always learning and adjusting to new and upcoming attack methods.

For example, Adobe improved its security by implementing user behavior analytics (UBA) to detect insider threats and unusual user behavior. The UBA uses machine learning to identify any deviations from normal activity, improving threat detection and data protection.

With UBA, Adobe can distinguish between high-severity threats that are not malicious and those that are truly malicious. For example, if a user travels to a new city and uses a new device or browser, UBA may flag this as a high-severity case, even though it is not malicious. UBA with machine learning has improved Adobe’s ability to detect insider threats accurately.

7. Endpoint detection and response (EDR)

Endpoint detection and response solutions are at the top of endpoint protection tech. EDR platforms keep a 24/7 eye on endpoints to spot threats and offer cutting-edge tools to dig deep and respond.

EDR solutions often include many features we discussed earlier, like antivirus, firewall, IDS/IPS, and ways to analyze behavior.

The best EDR platforms come with some key features:

• They monitor endpoints 24/7/365 and catch threats live and in background
• They respond and fix issues promptly
• They have advanced systems to detect threats
• They provide in-depth tools to investigate incidents
• They work well with other security systems to create a united defense plan

How Does Endpoint Protection Work?

An endpoint protection solution is installed on a server and every endpoint, establishing a central security system. It has many benefits for productivity and control such as:

1. Centralized monitoring and management: IT teams can monitor the security status of all devices from one dashboard. This central view cuts down the time and effort needed for security oversight, allowing IT teams to focus on big-picture items.
2. Global update deployment: One of the most useful features is sending updates to all endpoints simultaneously.

Here’s what else it does:

• Quick action against new threats: IT can roll out security patches across the whole network right away
• Maintains the same level of protection: All devices stay safe and it ensures continuous compliance
• Less disruption for users: Updates happen behind the scenes, so employees can keep working without any hindrances
• Less work for IT: No need to update each device one by one

1. Automatic threat spotting: The software continuously monitors devices, checking files, folders, programs, and network traffic to find vulnerabilities. This allows security teams to deal with more pressing security issues and plan ahead.
2. Quick threat handling: When it spots a threat, the software can :
   • Cut off affected files or systems
   • Stop fishy network traffic
   • Warn users and IT teams about the danger. This fast, hands-off response prevents potential security issues from causing too much trouble, allowing businesses to continue operating.
3. Application control: An essential part of endpoint security is the power to oversee which apps or programs users can get or install. This central oversight:
   • Cuts down the chance of malware attacks from unapproved software
   • Makes sure the company follows software license rules and its own policies
   • Makes software asset management easier

Implementing Endpoint Protection

An endpoint protection strategy involves deploying security solutions. It can detect, analyze, and respond to threats at the device level. Here’s a detailed step-by-step breakdown of how it is done:

Identify all of your endpoints

The first step to effectively manage and secure a network is identifying all connected endpoints. This provides a comprehensive view of the network’s scale and ensures that no device is left unprotected.

Why is this important?

Unidentified and unprotected endpoints can become entry points for bad actors to access the network and sensitive data. According to IBM, the average total cost of a data breach is 4.88 million. These security breaches can affect the company’s financial stability, reputation, and operations.

Considering the scale of these risks, taking proactive actions to discover all endpoints becomes crucial. But how do you ensure every device is accounted for?

While performing a manual inventory can be time-consuming and prone to human error, using network discovery tools such as Singularity™ Network Discovery can streamline the process. It enables a more efficient and thorough identification of all devices or endpoints within the network.

Consider a scenario where a remote employee receives a malicious email with a link to the document tagged as “urgent” and opens it unknowingly. This link downloads the malware onto the device, and the attacker gains access to the network and sensitive data. This example highlights how important it is to discover and protect your endpoints.

Assess vulnerabilities

Once all the endpoints are identified, assess the sensitivity of the data and rank them based on their potential impact on the network. This ranking allows for a prioritized approach to deal with threats and ensure effective allocation of resources.

Also, conduct a detailed analysis of potential threats, such as ransomware, phishing, and malware, to determine the level of risk involved with each endpoint. This helps prioritize the devices with high risk and take action to protect them, which leads us to the next step.

Select endpoint protection solutions

The next step is to implement strong security measures such as antivirus, firewall, encryption, data loss prevention and intrusion protection throughout the network. To implement these measures, consider an endpoint threat protection platform such as SentinelOne.

While choosing an EPP, research all the vendors, look for features your organization requires, compare pricing, and ensure the platform scales with your needs.

Evaluate vendor support and how the software impacts performance. In short, choose software with comprehensive coverage within your budget with good market reputation.

Deploy and configure solutions

Ensure the solution you choose integrates with your operating system, network, servers, databases, and other security tools. Test to see whether the new EPP is operational without any problems.

Then, deploy the EPP agent on target devices and define security policies, such as firewall rules and antivirus settings, access controls, and whitelisting or blocklisting to ensure only authorized applications can run.

Monitor and review security protocols

Identifying all endpoints, installing EPP solutions, and educating employees is only part of the solution.

To have a complete solution:

1. Monitor the network and performance of the security solution in real time.
2. Conduct regular audits of the security infrastructure to identify potential weaknesses.
3. Review and update the security protocols based on the findings from audits and incident reports.

Endpoint Protection Strategies

Endpoint protection strategies involve a combination of advanced threat detection and machine learning capabilities. They use real-time response mechanisms to identify and neutralize threats before they can cause significant damage.

Here are some strategies for your organization to follow:

1. Offer layered security

Even though protecting your organization starts with a firewall filtering the data packets, it requires more than just a firewall to face modern threats in the cybersecurity space. An organization requires protection at various stages, including email-specific antivirus, IoT devices, cloud security, remote devices, servers, mobile device management, etc. Each stage carries a different risk level and requires a different approach to mitigate them. So, security professionals must ensure protection across all these layers by implementing a comprehensive strategy.

2. Educate users

Start the training with the basics, such as accessing and navigating the EPP platform, understanding settings and controls, and reporting suspicious activity. Additionally, the training material should be updated to reflect the software changes. Then, remind employees about the best practices by implementing a notice board mechanism that is always visible to everyone.

Some of the best practices are:

• Create strong, unique passwords that are longer than eight characters
• Avoid sharing passwords with others
• Follow safe browsing habits such as browsing only authorized and popular websites
• Be cautious when opening a link. If it seems suspicious, report it to the management
• Educating oneself about how phishing and social engineering attacks occur to prevent them from happening in the future

3. Regular updates and patches

The 2023 Data Breach Report by ITRC showed that there has been a 72% point increase in total compromises as compared to 2021. This growth indicates that cyber attacks are evolving, which increases the need for updated security patches to counter these new threats. So, regularly send updates or patches to improve the security of your systems. Try to automate installing these patches or updates whenever possible to reduce human errors.

4. Mobile Device Management (MDM)

According to Backlinko, the global mobile users in 2024 is 4.88 billion, expected to reach 5.28 billion by 2025. These include BYOD devices, which pose a huge security risk for the companies.

Mobile device management becomes essential to monitoring, controlling, and securing these devices and enforcing policies such as data encryption and app restrictions.

By implementing robust MDM solutions, you are one step ahead in mitigating the risks associated with BYOD devices and protecting the data.

5. Incident response planning

Even with a firewall, antivirus, and EPP solutions in place, hackers sometimes find a way to infiltrate a network. Incident response planning commences in such situations by outlining steps to be taken, such as containment, eradication, recovery, and lessons learned. By having a clear plan in place, an organization can respond to these breaches immediately, minimizing the damage and data theft.

Endpoint Protection Use Cases

Endpoint protection platforms address a wide range of cybersecurity threats. Use cases range from securing endpoints to safeguard remote work environments to monitoring and controlling data access and transfer to ensure compliance with data protection regulations.

Here are some use cases in detail:

1. Providing remote remedies

When a security issue is discovered, teams often need to address it from various locations, such as home offices. EDR lets them investigate and fix issues remotely, no matter where they are, using cloud-based tools that give visibility into all connected devices.

2. Forensic investigations

After an attack, it is essential to investigate how it happened and how you can prevent it from happening again. EDR tools give a clear picture of the entire attack, making it easier to learn from the incident and close security gaps.

Choosing and Evaluating the Right Endpoint Protection Software

The endpoint protection platform you choose can have a big impact on your company’s security stance, how well it runs, and how it deals with new threats. As you look at different EPP options, consider the following essential parameters.
