How Businesses Can Strengthen Their Endpoint Security Strategy

Businesses rely on laptops, desktops, smartphones, tablets, servers, and other connected devices to perform everyday work. Each of these devices can provide access to company applications, networks, and sensitive information. As organisations become more dependent on digital systems and remote working, protecting these endpoints has become an important part of cybersecurity.

The global endpoint security market attained a value of USD 18.05 billion in 2025 and is projected to expand at a CAGR of 7.90% during 2026–2035, reaching USD 38.61 billion by 2035. The continued growth of the market reflects the increasing need for businesses to protect connected devices from malware, unauthorised access, data theft, and other cyber threats.

What Is Endpoint Security?

Endpoint security refers to the technologies, policies, and processes used to protect devices that connect to an organisation's network. These endpoints can include employee computers, mobile devices, servers, point-of-sale systems, and Internet of Things devices.

Traditional antivirus software remains one component of endpoint protection, but modern security strategies generally involve multiple layers. These can include endpoint detection and response, firewalls, application controls, encryption, vulnerability management, and identity-based security measures.

A strong endpoint security strategy therefore focuses not only on detecting threats but also on preventing attacks, monitoring suspicious activity, and responding quickly when an incident occurs.

1. Maintain an Accurate Device Inventory

Businesses cannot effectively protect devices they do not know about. Maintaining an up-to-date inventory of company endpoints should therefore be one of the first steps in a security strategy.

IT teams should track devices such as:

• Company laptops and desktops

• Smartphones and tablets

• Servers and virtual machines

• Remote and hybrid-work devices

• Connected IoT equipment

• Third-party devices with authorised network access

An accurate inventory helps security teams identify outdated systems, unmanaged devices, and endpoints that require additional protection.

2. Keep Operating Systems and Software Updated

Software vulnerabilities can provide attackers with opportunities to gain unauthorised access to devices. Regular patching can reduce exposure to known security weaknesses.

Businesses should establish a structured patch-management process covering operating systems, browsers, applications, drivers, and security software. Critical updates should be prioritised based on the severity of the vulnerability and the importance of the affected system.

Automated patch management can also help organisations maintain large numbers of devices without relying entirely on manual updates.

3. Use Endpoint Detection and Response

Modern endpoint security increasingly goes beyond traditional antivirus protection. Endpoint Detection and Response (EDR) solutions continuously monitor devices for suspicious behaviour and can help security teams investigate potential threats.

An EDR platform can collect information about processes, network connections, files, and other endpoint activity. When unusual behaviour is detected, security teams can investigate the event and take appropriate action.

This approach is particularly useful against threats that may not be immediately identified through traditional signature-based detection.

4. Strengthen Identity and Access Controls

Protecting the endpoint itself is only one part of security. Businesses also need to control who can access devices, applications, and company information.

Multi-factor authentication can add an additional layer of protection by requiring users to provide more than one form of verification. Organisations should also follow the principle of least privilege, giving employees only the access they need to perform their responsibilities.

Regularly reviewing user accounts and removing unnecessary permissions can further reduce the risk of compromised credentials being used to access sensitive systems.

5. Encrypt Sensitive Data

Encryption can help protect information stored on endpoints. If a laptop or mobile device is lost or stolen, encrypted data is more difficult for unauthorised individuals to access.

Businesses should consider encryption for devices that store sensitive customer, financial, employee, or business information. Encryption should also be supported by appropriate key-management practices and access controls.

6. Secure Remote and Hybrid Work

Remote work has expanded the number of locations from which employees access company resources. Devices may connect through home networks, public Wi-Fi, or other environments outside the organisation's direct control.

Businesses can strengthen remote endpoint security by using secure access technologies, device management, multi-factor authentication, and regular security updates.

Employees should also understand basic security practices, such as avoiding unknown downloads, recognising phishing attempts, and reporting suspicious activity quickly.

7. Control Applications and Downloads

Unauthorised software can introduce security risks. Businesses should establish policies defining which applications employees are permitted to install and use on company devices.

Application allowlisting can restrict systems to approved software, while endpoint security tools can detect potentially harmful applications.

Controlling software installations can also reduce the risk of shadow IT, where employees use applications or services without formal approval from the organisation's IT or security teams.

8. Train Employees Regularly

Technology alone cannot eliminate endpoint security risks. Employees interact with company devices every day and can unintentionally create security problems by clicking malicious links, downloading unsafe files, or using weak passwords.

Regular security awareness training can help employees recognise phishing emails, suspicious attachments, social engineering attempts, and other common threats.

Training should be practical rather than limited to annual compliance sessions. Short updates, simulated exercises, and clear reporting procedures can help employees develop better security habits.

9. Monitor Endpoint Activity

Continuous monitoring can help businesses identify unusual activity before it develops into a larger security incident.

Security teams can monitor login attempts, software behaviour, network connections, file changes, and other indicators of suspicious activity. Centralised security platforms can bring information from different endpoints together, making it easier to investigate potential incidents.

Automated alerts can also help security teams prioritise events that require immediate attention.

10. Prepare an Incident Response Plan

Even strong security controls cannot guarantee that an organisation will never experience a cyberattack. Businesses should therefore prepare for incidents before they happen.

An endpoint incident response plan should establish:

• Who is responsible for investigating an incident

• How affected devices will be isolated

• How evidence will be collected and preserved

• How systems will be restored

• When customers, employees, or authorities need to be notified

• How lessons from the incident will be incorporated into future security measures

Regular testing can help organisations identify weaknesses in their response procedures.

The Role of AI in Endpoint Security

Artificial intelligence is increasingly being explored as a tool for identifying unusual endpoint behaviour. AI-based security systems can analyse large volumes of activity and help security teams identify patterns that may indicate a potential threat.

Machine learning can also support behavioural analysis by establishing baselines for normal device activity and identifying deviations.

However, AI should complement rather than replace security professionals. Alerts still need appropriate investigation, and automated actions should be carefully controlled to avoid disrupting legitimate business activity.

Challenges in Endpoint Security

Businesses face several challenges when implementing endpoint security. The number of devices can grow quickly, particularly in organisations with remote employees and bring-your-own-device policies.

Legacy systems can also be difficult to protect because they may not support modern security technologies or receive regular updates. Another challenge is the shortage of cybersecurity professionals who can monitor and respond to security events.

Organisations therefore need to balance security requirements with available resources. A risk-based approach can help businesses prioritise their most important systems and vulnerabilities.

The Future of Endpoint Security

Endpoint security is likely to become more integrated with broader cybersecurity strategies. Businesses may increasingly combine endpoint protection with identity security, cloud security, network monitoring, vulnerability management, and security analytics.

As cyber threats become more complex, security teams will also need greater visibility across devices and users. Automated detection and response technologies can help reduce the time required to identify and contain threats.

The growing use of cloud applications, remote work, mobile devices, and connected technologies will make endpoint protection an ongoing business requirement rather than a one-time IT project.
