What to Look for in a Pen Testing Firm in Manchester
Not all pen testing firms can handle the increased cyber risks and compliance scrutiny, particularly when working in a dynamic, complex environment like Manchester’s tech and enterprise ecosystem. What sets the best apart from the rest is this:

How to Choose the Right Pen Test Provider for Your Business

1. Review Their Sample Report
Look for:

2. Validate Industry Experience
Ask:
- Have they worked with companies in your vertical (SaaS, legal, NHS)?
- Can they speak to similar compliance requirements or data handling obligations?
3. Evaluate Post-Engagement Support
The value isn’t just in the test—it’s what happens next:
- Will they walk your team through remediation?
- Is a retest included?
- Can they support SOC 2, ISO 27001, or CE+ preparation?
- Do they have CREST certified consultants
4. Confirm UK Compliance Familiarity
Ensure the vendor has expertise in:
- Cyber Essentials and CE+
- CREST Certifications
- ISO 27001 audit readiness
- NHS DSP Toolkit (for healthcare/public)
- Data residency and secure report handling
💡 Tip: Treat the first call like a penetration test—ask tough questions. The right vendor will respect it.
