Glasgow Coverage

Offensive and defensive coverage for Scotland's
largest city.

Glasgow's economy runs from the International Financial Services District along the Clyde to one of Europe's most concentrated space and satellite manufacturing clusters, plus major engineering, public sector, and university estates. Financial services firms face regulatory testing obligations; engineering and space businesses sit inside defence and critical supply chains where security assurance is now a contractual requirement. We cover both sides: CREST-accredited penetration testing to prove the perimeter, and 24/7 managed detection and response for Glasgow organisations that need eyes on glass around the clock.

Engagement Pipeline

How Engagements Run In Glasgow.

From first call to free retest. Every Glasgow engagement is managed by a named account manager with direct access to the testing team, no ticket queues between you and the people doing the work.

Step 01

Scoping & Fixed Quote

A free scoping call, usually within 24 hours of your enquiry, where a technical consultant (not a salesperson) defines what needs testing, agrees the approach, and produces a fixed quote. Glasgow clients can scope by video call or, where practical, in person via our Edinburgh office.

Step 02

Testing In Glasgow

CREST Registered Testers execute the engagement during agreed windows: remote phases for external, web, and cloud testing, and on-site or appliance-based delivery for internal and wireless work in Glasgow. You get daily progress updates, and critical findings are escalated immediately rather than saved for the report.

Step 03

Reporting Built for Two Audiences

Every report contains an executive summary your board and customers can read, and a technical annex your engineers can action: reproduction steps, evidence, CVSS scoring, and specific remediation guidance. Reports are quality-assured before delivery and structured for auditors, insurers, and customer due diligence reviews.

Step 04

Debrief & Free Retesting

A full debrief walks your team through findings and attack chains, in person in Glasgow or at our Edinburgh office where practical, or by video call. Once you have remediated, we retest the fixed findings free of charge and issue updated reporting, so your evidence shows issues closed, not just found.
