Certified-grade penetration testing aligned to ISO 27001, SOC 2 and investor due-diligence.

Evidence Over Noise

We report what we find and verify - clearly, accurately and without exaggeration. No inflated or fear-based language - just defensible, audit-ready security findings that you can get behind. Our reports are structured to support ISO 27001, SOC 2, Cyber Essentials Plus and other assurance frameworks.

Operationally Aware Pentesting

Security testing should support delivery and business continuity, not derail it. We work in step with your engineering, compliance and senior leadership teams, balancing risk, business reality and audit requirements.

Senior-Led Accountability, Always

Every engagement is delivered by highly experienced, qualified penetration testers and a Technical PM — not junior staff or outsourced contractors. You get consistent quality, direct communication, and accountability from start to finish.

Working Alongside Your Team

We regularly collaborate with ISO 27001 and SOC 2 consultants, internal compliance and risk teams, fractional and in-house CISO/CTOs, Leadership and Founders. We integrate cleanly into existing workflows, reporting structures, and timelines — operating as a senior extension of your internal team. You won’t need to chase us. You won’t need to translate our findings. You won’t need to manage the process. We understand what auditors require, what technical teams need, and what leadership expects — and we deliver.

Built for More Than “Passing the Audit”

Compliance is not the only goal. Resilience is. Our testing directly supports risk registers, remediation planning and validation, ongoing security maturity and continuous improvement cycles. We design engagements so the output is usable — not just presentable.

Sample Report

Our Pentest Reports contain extensive details of the vulnerabilities identified throughout our engagement. This example report gives an idea of what information you can expect to find and how we present our findings to both your technical and non-technical stakeholders.

01

What exactly is a
Pentest?

A penetration test, sometimes also referred to as Ethical Hacking, is a pre-arranged and fully agreed simulated attack of a technological asset. The different phases of a full engagement may vary but they typically comprise a pre-assessment call where you’ll express your objectives and needs, the pentest itself and the reporting phase that culminates in a full report delivered to you within five days after finalisation. If you wish, we typically recommend a post-assessment call to allow both teams to discuss the results of the engagement.

02

How often should I have a Pentest?

Businesses are generally advised to conduct a pentest at least once a year, as well as after any migrations, significant upgrades or modifications to their network. However, Azacus strongly advise on quarterly pentesting due to the speed at which new exploits are identified. Regular testing is often required for compliance with regulations such as PCI DSS.

03

How long will a Pentest take?

This varies based on the scope of the test but can be anything from a couple of days to weeks. Things that can affect the length of an engagement include the type of the test itself, network or application size, if it is internal or external facing, client-side technical limitations, etc.

04

Pentesting vs Automated Scans?

I run regular vulnerability scans, isn’t that enough?  Vulnerability scanning comprises an automated scan executed by a program, whereas Pentesting combines this approach with manual testing and exploitation of vulnerabilities to provide a much more in-depth assessment of hidden weaknesses. Pentesting is much more akin to “real” malicious hacking.

05

Is Pentesting necessary for smaller businesses?

I’m a small company with limited budget but I know I need my cybersecurity tested – is Pentesting available for me?  The short answer is yes. Azacus services range in size and cost but our team will work with you to provide the most comprehensive and useful package based on your budgets. We always recommend putting cybersecurity high on your list of priorities; with the average cost of a data breach currently over £2m, the alternative can be devastating.

06

What should I do with my Azacus Pentest report?

We always recommend reading your Pentest report in full, with the support of your wider technical team. Mitigation of vulnerabilities can be provided by a number of cybersecurity managed services companies ahead of a retest to ensure all changes have been effective. We also offer a call with the lead tester to run through the report with you and/or your technical team if desired.
