Put your network security to the test

By using all the tools and tricks available to real-world attackers, our network and infrastructure penetration tests uncover weak points in your IT security. The result is an easy-to-understand comprehensive report which explains each discovered threat and even drills down into key remediation advice. Infrastructure testing is often combined with application testing for total threat protection.

Bulletproof your cyber security

The threat landscape is always evolving, so your cyber defences need to work hard to keep you secure. Regular network penetration testing is an easy way to manage your vulnerabilities and ensure your infrastructure stays protected against hackers. Periodic penetration testing is also a requirement of many security standards, including ISO 27001 and PCI DSS.



Building strong security foundations

Along with protecting from direct attacks, penetration tests are also the bedrock of a strong risk management strategy. They improve your overall security posture and help make sure you have total control of your systems, network and infrastructure. Penetration tests can also be mixed with our other security services to create a complete threat protection package, such as threat management (SIEM).

Frequently asked questions

What is network penetration testing?

A network penetration test (also called an infrastructure penetration test) is where a qualified professional takes on the role of a hacker and attempts to gain access to or compromise your infrastructure in some way. Any misconfigurations or vulnerabilities are then reported back to the business so that they can be resolved, and the threats mitigated. The ultimate goal of a penetration test is to help businesses harden their security.

Learn more about penetration testing from our in-depth guide.

Is there a report delivered at the end of the test?

When the testing is complete we’ll send you an easy-to-understand, thorough report. It contains two parts: an executive summary for a high-level management overview and a detailed technical run-through, complete with remediation advice and recommendations. A debrief call is also included to discuss the findings of the report and answer any questions.

What are the different types of network penetration test?

A network penetration test can be as simple or as in-depth as you require, tailored to your security and operational objectives. As a minimum, tests are run from an external perspective, where less is known about your infrastructure, simulating what a hacker would see before they’ve gained access to your network.

Larger tests include internal testing, where we examine your security from inside your network. This is a thorough test that simulates what damage a hacker could do if they breach your network perimeter.

There are other components to consider, including network segmentation testing, Wi-Fi testing and social engineering. We recommend a blend of these activities to make sure your tests meet your objectives whilst remaining cost-effective.

How long does a network penetration test take?

This varies, depending on the size of the infrastructure environment to be tested. As a rough guide, simple external tests can be completed in 2-3 days, medium-sized engagements with internal tests typically take 5-10 days, and larger-scale tests normally take 10+ days.

Will my systems be disrupted during a network penetration test?

We take great care to ensure we don't disrupt your systems and always minimise the impact of our testing activities. We can also include specific requests, such as no DoS (denial of service) activity.

What standards do you work to?

Bulletproof work in accordance with industry best practices, including the Penetration Testing Execution Standard (PTES) methodology. In addition, our staff hold recognised certifications such as CREST and Tigerscheme.

Do you offer free retests?

It’s important to ensure your remediations have mitigated the vulnerabilities discovered by our tests. That’s why Bulletproof offer free retests of all uncovered vulnerabilities as standard, accompanied by an updated report.

Do you recommend other tests to complement network penetration testing?

Hackers consider all layers of the technology stack, so we recommend also testing the apps and services running on the infrastructure, including web and mobile applications. Nothing is out-of-bounds to hackers, so Bulletproof always recommend including elements of social engineering, and even offer full red team security assessments.
