Penetration testing to meet the challenges of enterprise

Penetration testing at the scale of enterprise organisations comes with additional challenges. In addition to ensuring quality tests from a trusted provider, enterprises require a planned approach and a pen testing service that can cater for managing multiple test regimes. The wider nature of an enterprise’s attack surface, with challenges of legacy and shadow IT, means that a pen test provider must provide accurate scoping to get meaningful test outcomes.

There are also many different drivers for an enterprise’s full-stack pen testing needs, including DevSecOps, CISO, GRC, product owners and more. Where in-house testing teams exist, internal tests may not be as thorough or unbiased as external penetration testing from a trusted provider, and compliance requirements often demand third-party penetration testing.

Bulletproof’s enterprise penetration testing meets all these challenges head-on to deliver a service that makes it easy to manage multiple tests and get the best outcomes.

Enterprise pen testing FAQs

Enterprise penetration testing, commonly just called pen testing, is an ethical simulated cyber attack on an enterprise’s IT & OT infrastructure. The goal is to enumerate security weaknesses, so that cyber vulnerabilities can be codified, prioritised, and remediated. The methods and tools of enterprise penetration testing vary with on what’s being tested and the scope of the test. Networks, systems, web apps, mobile apps, cloud environments, build images, IoT/OT and humans all present security vulnerabilities to enterprises.

Penetration testing from a reputable pen test service provider is required or recommended by a wide range of compliance standards and certifications. Bulletproof’s enterprise penetration testing can help enterprise organisations meet and maintain compliance with:

  • ISO 27001
  • SOC 2
  • FTC Safeguards
  • GDPR
  • And more

Bulletproof’s dashboard-driven SaaS platform makes it easy to see at-a-glance prioritisation of your pen test findings, giving enterprises intel on what you need to fix first. With limited remediation budgets, the threat management feature of the portal helps enterprises get maximum impact from their remediation efforts. Threats from other services, such as managed SIEM are also displayed here, giving a powerful single pane of glass overview of your security posture.

Enterprise organisations undertaking penetration testing often have different operational and security objectives compared to SMEs and startups. Whereas an SME might say ‘test everything’ and undertake pen testing once a year, an enterprise will have separate pentesting programmes for different infrastructure components and business units. Enterprise pen testing providers will be able to facilitate this kind of multi-testing approach, and also be able to work with an enterprise’s internal pentesting teams.

Bulletproof’s global teams of experienced pen testers use a variety of off-the-shelf and custom tools in their pentesting activities. For example, automated security scanning, custom-crafted scripts, commercial tools and hand-tailored exploits all combine with a pen tester’s insight and expertise to compromise your cyber defences. Our CREST certified penetration testers always use the right tooling for the task, using different tools and tech for asset enumeration, network discovery, attack surface mapping, exploitation, and so on.

Even in the enterprise landscape, there still exists confusion about which tool is best for your organisation: penetration testing or vulnerability scanning. This quick ‘cyber security 101’ video can help you understand the difference.
