What sets our services apart

The success of an engagement is directly linked to defining an appropriate scope

Adversify take the time to understand your environment and its attack surface. This allows us to create a penetration testing strategy that is unique to your organisation.

We prioritise real-world vulnerabilities and attack paths.

Adversify focus on vulnerabilities and misconfigurations that are commonly exploited by real-world adversaries.

Leaving your organisation with the results that matter to you.

We design our penetration testing engagements using an attack surface-led approach.

Without looking at the whole attack surface, it's not possible to truly provide security assurance.

Our approach ensures that the entire attack surface of the environment is analysed and assessed for weaknesses.

Adversify prioritise outcomes over time.

Our goal is to help your organisation achieve it's security goals and we appreciate that sometimes fixed-term engagements, don't always go to plan.

To make sure your organisation gets the most out of its penetration test, we design all our penetration testing engagements with a series of deliverables and are sold for a fixed project price. 

// The process

Our proven process to assess your defences

1

Engagement design

Using our attack surface-led approach, we work with you to design a penetration testing strategy that is unique to your organisation and encompasses any raised security objectives or concerns.

2

Analyse the attack surface

We invest time in understanding the exposed attack surface of the assessed system to identify attack vectors that present the biggest risks to your organisation.

3

Discover vulnerabilities and exploit attack paths

Our penetration testers assess the attack surface for vulnerabilities and misconfigurations, commonly exploited by real-world adversaries.

We conduct exploitation activities to identify attack paths and routes into the organisation, allowing you to visualise how a real-world adversary would breach your organisation.

4

Reporting and evaluation

All discovered findings are presented within a comprehensive and detailed Adversify penetration test report.

You'll have the opportunity to join a post-assessment discussion about the engagement, where we recap on any lessons learnt and can offer additional assurances about the security of the assessed environment.

FAQs

Some frequently asked questions about our pen testing services and our unique approach in comparison to traditional methods.

What makes Adversify’s Penetration Testing Services different?

While traditional penetration testing provides valuable baseline coverage, Adversify enhances this with our attack surface-led methodology to deliver wider and more targeted insights.

By incorporating the entire attack surface within the penetration test scope, it provides holistic coverage that aligns more closely with how real-world attackers operate. This approach ensures that no critical exposure is overlooked simply because it falls outside a predefined technology silo, ultimately delivering more actionable, relevant, and risk-prioritised results.

What is an attack-surface led approach to penetration testing?

Your attack surface includes all the systems, connections, applications, identities, and data that could be targeted whether they’re externally facing or internal but linked in ways that could be reached or misused.

Instead of testing individual systems in isolation, this methodology looks at how those systems connect and interact, building a complete picture of your exposure. It focuses on relationships and pathways how an attacker might move through your environment, chain weaknesses together, or exploit overlooked dependencies.

By taking this holistic view, testing becomes more intelligent, realistic, and reflective of how real-world attacks unfold moving beyond single vulnerabilities to reveal how genuine threats could emerge and impact your business.

Why is full attack surface visibility crucial for modern cybersecurity?

Even organisations with strong security controls can be vulnerable in ways that aren’t immediately obvious. Modern environments are complex with cloud platforms, third-party integrations, remote access points, and constantly changing assets.

Attackers don’t just look for obvious weaknesses, they look for opportunities such as exposed connections, forgotten systems, or misconfigured integrations that can open the door to something bigger.

Full attack surface visibility ensures you can see your organisation the same way an adversary does. By understanding every point of exposure, across people, processes, and technology, you can identify weak spots before they’re exploited, maintain stronger security posture, and stay ahead of emerging threats.

How often should a business conduct penetration testing on its attack surface?

The frequency of testing depends on your organisation’s security needs, risk profile, and rate of change. There’s no one-size-fits-all answer some businesses benefit from continuous or quarterly assessments, while others may only require annual testing.

As a general best practice, we recommend conducting penetration tests at least once a year and after any major infrastructure, software, or configuration change.

Regular testing ensures your defences stay aligned with your evolving environment and that newly introduced systems don’t create unseen exposure across your attack surface.

How does Adversify help identify the attack surface for our business?

We begin every engagement by understanding your organisation, not just its technology, but its operations, priorities, and potential exposure points. Through a focused scoping conversation, we work with you to explore how your environment is structured, what’s most critical to your business, and where you believe your greatest risks may lie.

From there, our team independently maps and validates your digital footprint to uncover assets, connections, and potential exposures that may not be immediately visible.

This combination of collaboration and discovery ensures we define an attack surface that accurately reflects how an adversary would view your organisation allowing us to deliver testing that’s focused, relevant, and truly representative of your real-world risk.
