What is Managed Security Service Provider?
Definition
Managed Security Service Provider (MSSP) is an external company that runs and monitors an organisation’s security controls — firewalls, endpoint protection, log collection, vulnerability scanning — and reports what it sees. Organisations use one for the reason they use any managed service: continuous coverage and specialist skills without building the team in-house. The question worth settling before signing is what happens after an alert: a traditional MSSP notifies, while an MDR service is engaged to investigate and contain, and confusing the two is the most common source of disappointment in outsourced cybersecurity.
Role in cybersecurity
Managed Security Service Provider plays an important role in building organizational resilience against cyber threats. Implementing appropriate mechanisms in this area is required by regulations such as NIS2, DORA and ISO 27001.
