What’s Considered An Endpoint?
An endpoint device refers to any device which connects directly with a corporate network from outside its firewall, including devices like routers. Examples of endpoint devices:
Laptops, tablets, mobile devices, Internet of Things (IoT) devices, Point-of-sale (POS) systems, switches, digital printers and any other devices that communicate with the central network are considered peripheral devices.
Why is Endpoint Security Important?
Endpoint security management is essential for organizations of all sizes because it helps protect against cyber attacks and data breaches. Cyber attackers target endpoints to access an organization’s network and steal sensitive data. According to a recent report, the average cost of a data breach is $3.86 million, and the cost per record lost or stolen is $150.
Endpoint security solutions employ a variety of methodologies, including behavioral analysis and machine learning, to promptly identify and obstruct threats. Real-time threat detection and prevention are key components of endpoint security. Additionally, endpoint security encompasses measures aimed at safeguarding data, such as implementing data encryption protocols and deploying data loss prevention mechanisms. These comprehensive approaches contribute to the overall protection and integrity of endpoint devices formally and professionally.
Components of Endpoint Security
Endpoint security is composed of various components designed to provide comprehensive protection to endpoints. The following are some of the essential components of endpoint security:
- Antivirus and Anti-Malware Software: Antivirus and anti-malware software are designed to detect, prevent, and remove malicious software that can cause harm to endpoints. This software uses a database of known malware signatures and behavioral analysis to identify and eliminate threats.
- Firewall: A firewall functions as a network security mechanism responsible for overseeing and managing network traffic, both incoming and outgoing, by implementing predetermined security regulations. It acts as a barrier between an endpoint and the internet to prevent unauthorized access to the network.
- Intrusion Detection and Prevention Systems: Intrusion Detection and Prevention Systems (IDPS) are purpose-built solutions that aim to identify and proactively hinder unauthorized access, misuse, and abuse of endpoints. These systems diligently observe network traffic, constantly scanning for any signs of suspicious activity. When potential threats are detected, IDPS promptly responds by taking necessary actions to mitigate risks and maintain the security of the endpoints. By employing these systems, organizations can bolster their defense mechanisms and effectively protect their network infrastructure.

- Data Loss Prevention: Data loss prevention (DLP) encompasses a comprehensive suite of security tools and policies designed to safeguard sensitive data from compromise, loss, or theft. It involves the implementation of robust policies, procedures, and technology to detect and prevent data breaches. By effectively identifying and mitigating potential risks, DLP measures enable organizations to maintain the confidentiality, integrity, and availability of their critical information assets. Through the adoption of these proactive measures, organizations can fortify their data protection strategies and mitigate the potential consequences of data breaches.
- Endpoint Detection and Response (EDR): Endpoint detection and response (EDR) is a security technology that detects, investigates, and responds to advanced threats on endpoints. It combines real-time monitoring, behavioral analysis, and forensic capabilities to detect and respond to sophisticated attacks.
- Patch Management: Patch management is the process of keeping software applications and operating systems up to date with the latest security patches. It is an essential component of endpoint security as it helps to prevent vulnerabilities from being exploited by attackers.
- Mobile Device Management (MDM): Mobile Device Management (MDM) refers to a security technology specifically designed to oversee and protect mobile devices utilized within the workplace environment. This comprehensive solution encompasses a range of policies, procedures, and technology aimed at ensuring that mobile devices are properly configured, secured, and kept up to date. By implementing MDM, organizations can effectively mitigate the risks of data loss and unauthorized access. MDM plays a critical role in maintaining the integrity and security of mobile devices, thereby bolstering the overall security posture of the organization.

How Endpoint Protection Works
Endpoint security refers to the practice of safeguarding data and workflows associated with individual devices that connect to your network. Endpoint protection platforms (EPP) work by inspecting files as they enter, while modern EPPs utilize cloud storage technology to maintain an ever-expanding database of threat information – freeing endpoints from local storage of all this data while simultaneously improving speed and scalability by accessing this information via the cloud.
EPPs give system administrators access to a centralized console installed on a network gateway or server and allow cybersecurity professionals to remotely control security for each device remotely. The client software can then be assigned to endpoints – whether as SaaS with remote management capabilities or installed directly onto devices – allowing security professionals to secure them remotely and manage corporate policies from one central location. Once set up, EPPs secure endpoints through application control (which blocks unapproved use) and encryption methods which help prevent data loss.
Installing and configuring EPP quickly allows it to detect malware and other threats quickly and reliably, with some solutions also including an Endpoint Detection and Response (EDR) component which detects advanced threats like polymorphic attacks, file-less malware and zero-day attacks by employing continuous monitoring capabilities – providing greater visibility as well as multiple response options for any detected breaches.
EPP solutions come in both on-premises and cloud-based models, with cloud offerings typically being more scalable and easier to integrate into existing endpoint security architecture; however, certain regulatory rules may necessitate on-premises for endpoint security compliance reasons.
Endpoint Protection Platforms (EPP) and traditional antivirus solutions differ significantly in several key aspects.
Endpoint and Network Security: Antivirus programs are typically tailored to protect a single endpoint, offering visibility only into that endpoint from its location. In contrast, endpoint security software allows an enterprise network administrator to gain visibility of all connected endpoints from one central location.
Administration: Traditional antivirus solutions required users to manually update databases themselves or allow updates at predetermined intervals, but EPPs provide interconnected security solutions which shift administrative responsibilities away from individual users and toward enterprise IT or cybersecurity teams.
Safeguard: Traditional antivirus solutions used signature-based detection to identify viruses. If your business was Patient Zero or users hadn’t updated their antivirus programs recently, your company was at risk. Thanks to cloud technology and technologies such as behavioural analysis, today’s EPP solutions stay up to date automatically, uncovering previously undetected endpoint security threats through suspicious behaviour analysis and uncovering threats previously undiscovered by traditional means.

Endpoint Security Best Practices
To ensure the security of endpoints, companies should adopt certain best practices. Here are some of the best practices for endpoint security:
Employee Education and Training
Employee education and training are critical for preventing security breaches. By educating employees about security policies and procedures, companies can prevent them from falling prey to phishing attacks and other social engineering tactics.
Regular Software Updates
Regular software updates are essential for endpoint security. Outdated software can contain vulnerabilities that can be exploited by cybercriminals. Companies should ensure that all software on their endpoints is up-to-date and patched regularly.
Password Management
Passwords are often the first line of defense against cyber threats. Companies should ensure that employees use strong passwords and change them regularly. They should also implement policies to prevent employees from sharing passwords and using the same password for multiple accounts.
Use of Multi-Factor Authentication
Multi-factor authentication is an invaluable security measure that enhances the protection of endpoints. This approach mandates users to provide multiple forms of identification, beyond just a username and password, to gain access to their accounts. By enforcing multi-factor authentication, organizations fortify their defenses and effectively mitigate the risk of unauthorized access to endpoints. This additional layer of security significantly reduces the chances of unauthorized individuals breaching sensitive data and reinforces the overall security posture of companies.
Network Segmentation
Network segmentation involves dividing a network into smaller subnetworks to improve security. By segmenting their network, companies can prevent cybercriminals from gaining access to all of their endpoints at once. It also helps to contain the damage caused by a breach, as the data is present in subnetworks.
