What is an MSSP (Managed Security Services Provider?

A managed security service provider (MSSP) is an IT service provider that provides an organization with information security, cybersecurity monitoring and management, which may include policy development, security operation center, compliance services, incident response service, Virtual CISO, risk management program, vulnerability testing, penetration testing, security training and awareness, virus and spam blocking, intrusion detection, firewalls and virtual private network (VPN) management.

How does an MSSP differ from an MSP?

The extra “S” in MSSP indicates that it is more focused on security than a typical MSP. While MSPs are increasingly offering security services (some may even have an MSSP practice rolled into the larger MSP business), MSSPs are purely focused on security. However, even then, according to Keve, MSSPs can encompass a fairly broad umbrella of security services.


For example, MSSP technology offerings may include deploying, configuring, and/or managing the following technologies:

Furthermore, MSSP services may include:

An MSSP may offer a broad, generalized suite of security capabilities and services, or it may specialize in one or a few core focus areas. “Traditionally, MSSPs have been overwhelmingly focused on the perimeter,” assesses Keve. “And, while MSSP offerings are evolving, even today, few MSSP’s tackle IAM, which is a focus of Simeio.”

Another differentiation between MSPs versus MSSPs is NOCs versus SOCs. MSPs frequently establish their own network operation center (NOC) from which they monitor and administrate over customer operations, MSSPs on the other hand typically establish a security operations center (SOC), which is responsible for protecting the infrastructure (networks, applications, databases, servers, etc.). However, as Keve notes, “if an MSP takes security seriously as part of its business, it may also operate a NOC.”

Organizations will commonly rely on both an MSP and an MSSP.  “At Simeio, we work primarily with our clients, but we will often interoperate with functions out-sourced to a third-party, such as an MSP,” says Keve.

Understanding managed security service provider (MSSP)

MSSPs are best defined as IT experts who zeroed in on improving digital security. These groups provide everything, from firewalls to intrusion detection monitoring, spam blocking, virus blocking and the management of private networks. Some MSSPs offer additional features, ranging from upgrades to system alterations and beyond.

What matters most is whether the provider in question earns its keep. Take some time to perform research on prospective MSSPs. Do not stop digging until you find a provider with glowing references, excellent reviews, and a polished website.


You should know exactly what you need from an MSSP prior to making a commitment or even researching candidates. Once you know exactly what your company needs, ensure that the provider in question is capable of actually delivering the promised services. If a candidate seems incapable of providing even one of the services your business needs, rule them out right away.

What managed security service providers are used for

MSSPs have their own unique specialties, merits, and weaknesses. Though these companies generally do the same things, one might be ideally suited for your business, while others aren’t suitable for your unique operations. Find a cyber security group in New York with a proven track record in your industry, ensure their terms, costs, manpower and expertise are a fit and there will be a seamless integration into your business.

Why do organizations rely on MSSPs?

It is important to generate a nuanced service level agreement with the MSSP you favor. This agreement guarantees both parties fully comprehend each’s expectations and requirements. The relationship should ultimately prove mutually beneficial. If you are even slightly suspicious the MSSP is incapable of safeguarding your digital information, clients, employees, and business, move on to the next candidate. In the end, a group that does not earn its keep should not be trusted to protect your most important information.
