How We Get Your Pentest Started Quickly

Step #1: Confirm Your Scope & Objectives 

We’ll confirm the assets you want tested, agree on the right methodology (black box, grey box, etc.) and align on compliance requirements (UK GDPR, PCI DSS, ISO 27001, etc.). You’ll also choose your testing cadence, whether it'll be one-time, on-demand, or continuous.

Step #2: Schedule Testing

Once scope is set, you choose when testing begins. Our certified pentesters can start within days without long waits or rigid timelines thanks to our human-led, AI-accelerated approach.

Step #3: Your Pen Test Begins

Our in-house experts test your environment while the BreachLock Unified Platform lets you monitor their progress in real time. You can review findings as they appear and collaborate directly with testers so you can start prioritising and remediating findings immediately.

Step #4: Remediate, Validate Fixes, & Get Final Reports

As you remediate, you can automatically retest most vulnerabilities from the BreachLock Unified Platform to validate fixes. When you finish remediating, we perform a full manual re-test and provide updated, audit-ready reports proving that critical risks are truly resolved.

Frequently Asked Questions:

How long will my penetration test take?

Penetration testing is a time box activity performed based on your specific requirements, which can take anywhere from a few days to a couple of weeks, depending on the scope, complexity, functionality, interconnecting components, underlying technology, etc. Speaking with one of our experts is the best way to establish a well-defined time frame.

How much will my penetration test cost?

BreachLock’s pricing is based on the scope of your organisation’s unique testing requirements and is determined by the size and complexity of your environment and desired testing frequency. When you reach out, our in-house, certified pentesting experts will work with you to scope your project and deliver a project plan and a quote that aligns with your requirements and budget.

Will a pentest disrupt my business operations?

BreachLock takes every precaution to minimise disruption to your business during penetration testing exercises. BreachLock has a deep bench of certified penetration testers across multiple time zones to ensure testing is not conducted during peak hours. Additionally, BreachLock’s experts use proven methodologies, tools, and frameworks to avoid high-risk activities. With BreachLock, you have the ability to schedule your pentest when it’s most convenient for you.

What format does BreachLock provide reports in?

BreachLock clients can easily generate customised reports tailored to different stakeholder needs. From detailed technical reports for security and DevOps teams, to audit-ready reports with clear traceability for auditors, to high-level executive summaries, all reports can be generated directly from the BreachLock platform and downloaded in PDF or CSV format.

What information do I need to provide to start my pentest?

When we start the on-boarding process based on the agreed upon scope, you'll receive detailed instructions outlining what we'll need from you before penetration testing begins, whether it be IP addresses, URLs, authentication tokens, etc.
