Managed Service Security Provider (MSSP)

What is a Managed Service Security Provider?

A Managed Security Service Provider (MSSP) is a specialised third-party company that offers comprehensive cyber security services to organisations. MSSPs take on the responsibility of managing and enhancing the security posture of their clients by providing a range of security services, often on a subscription or service-based model. The primary objective of an MSSP is to protect its clients from cyber threats, monitor security events, and respond to incidents promptly.

What services does an MSSP provide?

Security Monitoring and Threat Detection

MSSPs continuously monitor their clients’ networks, systems, and applications for signs of security threats. Advanced tools and technologies are employed to detect and analyse security events, including suspicious activities and potential breaches.

Incident Response and Management

In the event of a security incident or breach, MSSPs have dedicated teams equipped to respond swiftly. This includes investigating the incident, containing the threat, and implementing measures to prevent further damage.

Vulnerability Management

MSSPs assist clients in identifying and addressing vulnerabilities in their IT infrastructure. This involves regular security assessments, penetration testing, and the implementation of patches and updates to mitigate potential risks.

Security Information and Event Management (SIEM)

They deploy SIEM solutions to aggregate and analyse security data from various sources. SIEM enables real-time monitoring, correlation of events, and the generation of alerts for potential security incidents.

Managed Firewall and Intrusion Prevention Systems (IPS)


Firewall and IPS solutions are managed and configured to control network traffic, prevent unauthorised access, and detect and block malicious activities.

Endpoint Security

With a focus on securing endpoints such as computers, laptops, and mobile devices, they also deploying and managing antivirus software, endpoint detection and response (EDR) solutions, and other security measures.

Security Awareness Training

Many MSSPs offer training programs to educate employees about cyber security best practices, reducing the likelihood of human-related security incidents, such as phishing attacks.

Compliance Management

MSSPs help clients navigate and comply with industry-specific or regulatory cybersecurity requirements. This is crucial for organisations that need to adhere to standards like GDPR, HIPAA, or PCI DSS.

Threat Intelligence

The latest cyber security threats and trends are closely monitored by MSSPs. They leverage threat intelligence to enhance their clients’ security measures, ensuring they are well-prepared against emerging threats.

By outsourcing security functions to a Managed Service Security Provider, organisations can benefit from specialised expertise, 24/7 monitoring, rapid response capabilities, and access to advanced security technologies. MSSPs play a vital role in helping businesses strengthen their cyber security defences and navigate the evolving landscape of cyber threats.
