A practical guide for UK SMEs
MSP vs MSSP: What Is the Difference?
An MSSP is a security specialist that delivers agreed security services for a business. The useful question is not whether a provider uses the label — it is what people, technology, hours, evidence and escalation the written service actually includes.
What exactly happens when an alert arrives?
Ask who reviews it, during which hours, what evidence is retained and who is responsible for the next decision.
Start with the definition
What is a managed security service provider?
A managed security service provider helps an organisation operate selected security controls and respond to security information under an agreed scope. That can range from endpoint configuration and scheduled alert review to a round-the-clock detection and response operation. Those are very different services, so ask for the detail.
MSP
A managed service provider usually looks after broader IT operations: devices, users, systems and support.
MSSP
A managed security service provider focuses on defined security controls, oversight, reporting and escalation.
MDR
Managed detection and response generally describes a more specialised detection and investigation service, often with active response and defined coverage hours.
Your scope
The contract should say what is monitored, when it is reviewed, who acts, how long evidence is retained and where responsibility sits.
How it works
A better way to compare providers
The detail behind the acronym matters more than the acronym itself.
Name the risk
Start with devices, users, data, suppliers and the incidents your team would struggle to handle alone.
Choose the service depth
Separate endpoint management, scheduled review, continuous monitoring and response rather than blending them together.
Write the boundaries
Record coverage hours, alert routes, log retention, responsibilities, exclusions and incident escalation.
Review the evidence
Ask for reporting that shows what happened, what changed and which decisions remain with you.
Due diligence
HCMA’s place in that picture
HCMA Softtech provides endpoint-focused security around Bitdefender GravityZone: setup, policy configuration, agreed-schedule monitoring and alert review, reporting, device changes, software installation and activation support, and UK remote help. This is not a comprehensive enterprise MSSP, continuous 24/7 SOC or MDR service. Both HCMA and Bitdefender provide 24-hour Bitdefender technical support, which is not the same as continuous monitoring or guaranteed incident response.
For an independent UK perspective, see the NCSC guide to choosing an MSP. It highlights checks such as verifiable credentials, references, access security, shared responsibilities, log retention, escalation, written service levels and third-party dependencies. It is guidance, not an endorsement of HCMA.
Ask before you sign
- Who reviews alerts, and during which hours?
- What logs are kept, for how long, and who can access them?
- Which incident actions belong to us, you or another supplier?
- What evidence and reporting will we receive?
Useful questions
MSSP questions, answered
No. An MSP may provide broad IT operations and include some security work, while an MSSP has a defined security-focused service. Check the actual controls, people, coverage hours and escalation terms rather than relying on the label.
It can be, when the scope matches the business. An SME may benefit from help with endpoint coverage, policy decisions, scheduled alert review and reporting without buying an enterprise SOC. Start with the risks and decisions your team needs help with.
There is no useful universal price. Cost is affected by device and user numbers, technologies, coverage hours, alert volume, log retention, reporting, response responsibilities, onboarding and compliance needs. Ask for the assumptions behind every quote.
Check verifiable qualifications and references, access security, shared responsibilities, log retention, incident escalation, written service levels and third-party responsibilities. The UK NCSC’s guide for choosing an MSP is a useful independent starting point.
