Choose a provider whose people understand your setup and are ready to act, not just a tool ticking over in the background. Check for:
- 24/7 monitoring and rapid incident response
- In-house engineers rather than an outsourced SOC
- Layered protection across endpoints, email, and cloud
- Backup and recovery for when things go wrong
- Cyber Essentials and ISO support
- Accreditations like Cyber Essentials Plus and ISO 27001, plus CREST-accredited penetration testing
Those accreditations show a provider is held to recognised standards, and that any security testing meets the same bar.
