Offensive Security & Testing
Find out how an attacker would get in, how far they would get and what to fix first, tested safely by experienced ethical hackers and backed by clear evidence.
Is this for you?
You might need this if…
You’re launching a new application, cloud platform or customer portal and need to know it holds up before going live.
A customer, auditor or regulator asks for an independent penetration test report.
You’ve invested heavily in security controls but have never tested whether they stop a real attack.
You’re adding an AI assistant or chatbot and don’t know how it could be manipulated into leaking data.
What we deliver
What it covers
Penetration testing
Experienced testers attack your web applications, APIs, internal and external networks and cloud environments the way a real adversary would. You get verified findings ranked by risk, with clear steps to fix them.
Red teaming and attack simulation
Goal-based attack simulations against people, processes and technology test whether your organisation detects and stops a determined attacker. For financial entities, we support preparation for threat-led penetration testing (TLPT) under DORA.
Application security testing and code review
We combine automated scanning with manual code review to find vulnerabilities early in development, when they are cheapest to fix. We also help build security testing into your pipelines so it runs with every release.
AI and LLM security testing
We test AI assistants, chatbots and agents for prompt injection, data leakage, unsafe tool use and jailbreaks, guided by the OWASP Top 10 for LLM Applications. You learn what your AI could be tricked into doing before someone else does.
Social engineering assessments
Controlled phishing, phone pretexting and physical access tests show how easily people can be manipulated into giving access. Results feed directly into targeted training, not blame.
Our approach
How we work
01
Scope
We agree targets, objectives, rules of engagement and test windows, based on your critical assets and the threats you realistically face.
02
Test
Specialists combine tools and manual techniques to find and safely exploit weaknesses, escalating critical issues immediately.
03
Report
Findings are documented with evidence, business impact and fix guidance, and walked through with your technical and management teams.
04
Retest
Once fixes are in place, we retest to confirm the weaknesses are actually closed.
Best practices
What we bring to every engagement
Test what matters to the business
Scope is driven by critical assets and realistic threats, not just a list of IP addresses.
Manual expertise over scanner output
Tools find the obvious; experienced testers chain small weaknesses together the way real attackers do.
Safe by design
Clear rules of engagement, agreed test windows and emergency contacts protect production systems.
Findings developers can act on
Every finding includes proof, impact and concrete guidance on how to fix it.
Always retest
A vulnerability is only closed when a retest confirms the fix works.
Test regularly, not once
Attack surfaces change with every release, so testing follows major changes and runs on a regular cycle.
Outcomes
What you get
- Verified vulnerabilities, ranked by business risk
- Proof-of-concept evidence and documented attack paths
- Clear remediation guidance for each finding
- An executive summary for management and auditors
- Retest confirmation of fixed issues
- Recommendations to improve detection and response
AI-powered
Unleash the power of AI
We offer the possibility of using AI throughout this work: ready-to-use AI tools, or a customised version built for your organisation that can run inside your own infrastructure. In offensive security, AI speeds up reconnaissance, maps attack surfaces and helps testers analyse large codebases and test results, so they spend more time on the creative attack paths automated tools miss. All testing stays under human control, within the agreed rules of engagement.
Starter offer
Attack Surface Assessment
A fixed-scope, three-week test of your internet-facing systems that shows what an external attacker can find and exploit, with a prioritised plan to fix it.
Days 1–3
Scope
Kick-off, agreement on scope and rules of engagement, and discovery of your internet-facing domains, services and applications.
Days 4–10

Manual and automated testing of exposed services, remote access and key web applications.
Days 11–13
Report
Findings validated, ranked by risk and documented with evidence and remediation guidance.
Days 14–15
Review
Walkthrough of results with your technical team and a summary for management.
You receive
- A map of your external attack surface, including forgotten assets
- Verified vulnerabilities ranked by risk
- Remediation guidance for each finding
- A management summary and an option for a follow-up retest
FAQ
Frequently asked questions
How often should we run penetration tests?
Many organisations test critical systems at least once a year and after significant changes such as new applications, major releases or migrations. Regulations and customer contracts may set their own requirements, which we help you interpret.
How long does a penetration test take?
A focused test of a single application or the external perimeter typically takes one to three weeks including reporting. Red-team exercises usually run over several weeks, with time for planning and debriefing.
Will testing disrupt our production systems?
Testing is planned to avoid disruption: scope, test windows, emergency contacts and excluded techniques are agreed in advance. Higher-risk tests can be run against test environments or outside business hours.
Who carries out the tests?
Tests are performed by specialists from our partner network, selected for the type of target, such as web, cloud, OT or AI. Altechy remains your single point of contact, manages scope and quality, and coordinates retests and remediation with your teams or existing suppliers.
