# Penetration testing & security assessments

The riskScanners report weaknesses in theory. A skilled attacker chains them together, and it's only when someone actually tries that you find out which ones lead somewhere.

Customers, insurers and tenders increasingly ask for evidence of recent testing, and a vulnerability scan often isn't enough.

 What it does- External penetration testing of your internet-facing systems
- Internal testing: what an attacker, or an insider, could do once inside your network
- Wireless testing, including spotting unauthorised access points
- Web application security assessments
- Goals agreed with you up front, so testing focuses on what matters to your business
- A full report of what was tested, what was found and what to do next
- Critical and high-severity findings retested once you have fixed them (within 90 days)

 Who it's forBusinesses asked for a penetration test by customers, insurers or tenders, those working towards ISO 27001, and any business that has made a significant change, such as a new system, a new office or a new website.

 How we supply itTesting is carried out by Sophos Advisory Services and arranged through us. We'll help you agree the scope, and we can help fix what's found at our standard day rate.

 What's under the hood**Sophos Security Testing & Assessment** — delivered by Sophos Advisory Services testers, whose findings also feed into Sophos Fusion.

 Questions How often should we test?+A common rule of thumb is at least once a year, and after any significant change such as a new system, an office move or a new website.

 Will testing disrupt our business?+Tests are planned with you, including timing and any systems to avoid, so they don't get in the way of normal work.

 Our tender asks for an accredited tester. Is that covered?+Tell us which accreditation is required when we scope the test, and we'll confirm the testers' credentials before you commit.
