Managed Security Services (MSS)

Managed security services (MSS) are comprehensive cybersecurity services offered by third-party organizations to monitor, manage, and enhance the security posture of an organization’s IT infrastructure. These services are designed to protect businesses from a wide range of cybersecurity threats with continuous monitoring of client assets using advanced tools such as internal and external vulnerability scanning, penetration testing, and network mapping. 

MSS will often include:

  • Managing firewalls to block potentially harmful traffic from an organization’s network.
  • Intrusion detection and prevention systems (IDS/IPS) to monitor for signs of data breaches.
  • Virtual private networks (VPNs) to secure remote access.
  • Regular vulnerability scans to identify weaknesses.
  • Advanced antivirus solutions to defend against malware.
  • Expert consulting to navigate cybersecurity compliance requirements and best practices.

One of the key benefits of using MSS is the cost efficiency compared to building these capabilities in-house or sourcing services across multiple cybersecurity vendors. As MSS providers spread these costs across a broader client base, they offer a more affordable solution for maintaining advanced security measures​​. Outsourcing MSS ensures cybersecurity practices scale as an organization grows and threats evolve. 

As threat actors are often located in different geographies — and nation-states continually target enterprise organizations — an MSS that incorporates a global perspective into emerging threats will enable faster response to new vulnerabilities.
