MSSP (Managed Security Service Provider)

An MSSP runs security services as a service: configuration, monitoring, tuning and response — 24/7 and with SLAs.

A managed security service provider (MSSP) operates security services for companies as an ongoing service: from firewall, WAF and Zero Trust access to monitoring, alert handling, response and reporting. The customer consumes protection as an outcome without having to maintain specialist knowledge and on-call rotations for every technology.

The difference to a classic IT service provider lies in the security focus and continuous operation: an MSSP keeps rulesets current, evaluates alerts around the clock and adapts protection to a threat landscape that changes weekly.

What an MSSP typically takes over

  • Operating and tuning protection platforms: WAF, bot management, DDoS protection, Zero Trust.
  • 24/7 monitoring with defined response and escalation paths (SLAs).
  • Incident support: triage, containment, follow-up.
  • Reporting for management and compliance evidence, for example under NIS2.

MSSP, MSP or your own SOC?

An MSP (managed service provider) runs IT infrastructure as a whole; an MSSP focuses on the security layer. Your own security operations center (SOC) is an internal team with full control — but high effort for staffing, shifts and tooling. Many mid-sized companies go hybrid: internal ownership of priorities and decisions, operational work at the MSSP.

KAEMI specialises in exactly this as a Cloudflare MSSP: we operate the security services of the Cloudflare platform as a managed service — from onboarding to 24/7 operations.

Frequently asked questions about MSSP (Managed Security Service Provider)

What distinguishes an MSSP from an MSP?

An MSP operates IT infrastructure in the broader sense — network, servers, workplaces. An MSSP specialises in security: protection platforms, monitoring, alert handling and response. In practice both roles complement each other; some providers, like KAEMI, fill both.

Does an MSSP replace an in-house SOC?

For many companies yes — at least the operational part. The MSSP takes over monitoring, triage and response in shifts while priorities and decisions stay in-house. That is usually more economical than building your own 24/7 team.

Which SLAs are common with an MSSP?

Typical are guaranteed response times per severity, defined service hours from 8x5 to 24/7 and rules for escalation and reporting. What matters is that the metrics are agreed measurably and reported regularly.

Does an MSSP help with NIS2?

Yes — NIS2 requires risk management, incident handling and evidence, among other things. An MSSP provides the operational foundation: documented processes, monitoring, response capability and reports usable in audits. Management responsibility remains with the company.

What does co-managed mean with an MSSP?

In the co-managed model, the internal team and the provider share the work: the company keeps defined areas — such as its own rules or certain systems — while the MSSP takes over operations, monitoring and on-call. The boundaries are drawn cleanly in the contract.

MTTR measures how quickly a service runs again after an incident — the metric that decides real downtime costs.

MPLS

MPLS forwards data packets based on labels over fixed paths and was for years the standard for connecting company sites. This article explains how the technology works and its strengths, shows its limits in the cloud era, and clarifies when SD-WAN is the better choice.

Multi-Factor Authentication (MFA)

Multi-factor authentication combines at least two independent proofs from knowledge, possession, and biometrics, and thereby renders stolen passwords largely worthless. This article explains methods from TOTP to passkeys, their phishing resistance, and how they differ from 2FA.
