Managed security services are network security services that are provided, managed, and maintained by a service provider. These vendors, referred to as a Managed Security Service Provider (MSSP), can deliver effective, custom, and robust security infrastructure to protect your organization. By outsourcing this task, your organization can benefit from not having to employ a dedicated IT team, as well as paying directly for the security tools and their management.

MSSPs offer advanced security features, a team of in-house experts, access to intelligence and data from sources all over the world, extensive threat knowledge, and threat mitigation. MSSPs combine threat detection, incident response, vulnerability management, and compliance support into one space, which can be purchased on a yearly or monthly rolling fee. Ultimately, MSSP take care of your security worries, so you don’t have to.

In recent years, threats and attacks have grown in sophistication and complexity. More money, time, and specialist knowledge is needed to help businesses protect themselves. Not every company, however, has the ability or resource to do this in-house. For those unable to meet this ever-growing security demand, investing in a managed service may be the answer.

In this article, we’ve put together a list of some of the best managed security services on the market. We’ll explore their key features, before breaking down some of the key questions in our FAQ sections.
