Benefits of penetration testing

Benefits of penetration testing

Benefits of penetration testing
50% of businesses and 32% of charities experienced a cyber security breach or attack in 2024
Penetration testing can identify complex and chained vulnerabilities that automated scanning can miss.
Gain insight into what areas of your system are vulnerable so that you can make informed decisions about where to invest.
Helps ensure compliance with standards like PCI-DSS and adhere to frameworks such as HIPAA, SOC 2, ISO 27001, and GDPR.
When you build, maintain or work within a system daily, internal bias can mask flaws, making it harder to detect vulnerabilities.
Methodology
We ensure testing has both depth and breadth by aligning with recognised methodologies such as CREST, OSSTMM, OWASP, and NIST.
We have a seven-step method.
We listen to your needs and develop a tailored project strategy, producing a scope that meets your unique requirements.
We assess your target systems and design a testing approach based on: where your organisation is most vulnerable, the most effective and efficient attack techniques, and how to conduct the test while ensuring your organisation remains protected.
We scan and enumerate the defined targets to identify existing vulnerabilities. This includes listening for open ports, identifying running services, and developing an attack plan based on the scan results.
Our consultants assess how deeply they can access your systems using leading industry techniques, custom-built tools, and their first-hand experience.
If a consultant successfully exploits a vulnerability, they assess its severity. This involves determining which assets and networks can be accessed and how much information can be gathered. Your vulnerabilities are then ranked from low to critical in GuardNest.
Findings are published in a report on GuardNest, organised by category and type, with remediation advice for each exploit and vulnerability. On request, we also arrange debrief calls, to review identified weaknesses in detail and discuss remediation.
Your GuardNest license includes continuous external infrastructure scanning to minimise risk between tests. We also offer a remediation check service, and every engagement includes a full consultative approach, ensuring we continue to support you even after the project is complete.

FAQs
A penetration test (or pen test) is a controlled, simulated cyberattack on your IT systems, designed to uncover security vulnerabilities before malicious actors can exploit them.
It mimics real-world tactics to assess how well your defences hold up across various environments, including networks, servers, web and mobile applications, and cloud infrastructure. The scope and techniques used vary depending on what’s being tested.
It is a requirement for many standards such as PCI DSS, ISO, SOC 2, HIPAA, FTC and more.
Vulnerability scanning, sometimes called automated penetration testing, uses software to methodically scan for known vulnerabilities. Penetration testing uses in-depth analysis and human ingenuity to uncover flaws that scanning alone can’t find.
Automated testing supports defences like regular patching, while penetration tests provide detailed reports and expert remediation advice. Pen testing companies often use both to protect your business from cyber threats.
CREST certified penetration testing ensures qualified professionals use recognised methodologies.
CREST is an international accreditation body certifying cyber security professionals and organisations. It ensures rigorous technical and ethical standards, supports compliance, and guarantees high-quality, repeatable testing.
We offer a variety of penetration tests, either as one-offs to spot check your security or on a recurring basis as part of an ongoing strategy.
The type of test depends on your security objectives, technology systems and compliance needs, and often a combination of tests is needed to meet an organisation's goals.
We can work with you to understand your goals and which tests will help you achieve them.
Penetration testing should be conducted at least once a year, with additional tests after significant infrastructure changes or upgrades. This schedule is supported by best practices, compliance standards and security professionals, and is mandated by standards like PCI DSS.
WorkNest Secure's penetration testing is designed to ensure minimal disruption to business operations. Testing can also be performed against a non-production replica of your live environment, such as a UAT or QA environment. A common specification is 'no denial of service (DoS)', meaning tests have a negligible impact on day-to-day operations.
The duration depends on scope, including whether it is internal or external, network size and complexity, and how much information is disclosed upfront.
With our GuardNest platform powering intelligent reporting, more time is dedicated to testing and less to writing reports, resulting in clearer outcomes and more cost-effective testing.
Penetration testing projects vary in length and complexity depending on factors like the apps and infrastructure being tested, the test’s aims, and its parameters. As a leading UK provider, we take time to understand your objectives to scope a best-fit test that delivers value for money. Our dedicated scoping experts help ensure the best outcome for your penetration test.
