11 Things I Wish I'd Known About Penetration Testing Firms Before Hiring One

The landscape of cybersecurity has become a labyrinthine expanse with the ever-increasing complexity and sophistication of threats. In this milieu, one of the robust fortifications a company can build is to engage the services of a penetration testing firm. While this may seem like a straightforward choice, the reality is replete with nuances and caveats that I only wish I had fully appreciated before embarking on this journey. Thus, I present to you, the reader, a distillation of my experiences and insights - 11 salient points I wish I’d been cognizant of before engaging a penetration testing firm.

• Penetration testing is not a corrective measure: Pen testing is akin to a litmus test, a gauge of the current state of your cybersecurity infrastructure. It identifies vulnerabilities, but it does not directly address them. The correctional measures post-discovery fall within the realm of other security practices. The onus of fortifying these weak points rests with your team or an outsourced cybersecurity firm.
• Penetration testers are not infallible: Like any other profession, the efficacy of penetration testers can vary. Even the most audacious and seemingly comprehensive pen test cannot guarantee the discovery of all vulnerabilities. It's a probabilistic model; the goal is to minimize the likelihood of a successful breach, not to eliminate it.
• Scope matters: The effectiveness of penetration testing is largely contingent upon the agreed-upon scope. In the context of cybersecurity, scope is not merely a question of breadth but also of depth. A comprehensive penetration test should delve deeply into the system, exploring all potential avenues of compromise, including web applications, network infrastructure, and even social engineering.
• Regularity is key: Cyber threats are not static. They evolve, adapt and proliferate at an alarming rate. Consequently, a one-off penetration test, however thorough, will not suffice. Regular checks that adapt to the changing threat landscape are imperative to maintain robust security.
• Not all pen testers are created equal: The cybersecurity industry is replete with countless pen testing firms. However, these firms differ in terms of their experience, expertise, and methodologies. There is an inherent trade-off between cost and quality, and it’s a delicate balance that requires careful consideration.
• Legal and ethical boundaries: A penetration test, by virtue of its nature, poses certain ethical considerations. It's essential that the rights and privacy of individuals are respected during the process. Legal stipulations, such as the use of exploits, also need to be adhered to.
• Pen testing and vulnerability assessments are different: While both practices work towards the same goal of enhancing security, their methods and focus differ significantly. Penetration testing is more dynamic, simulating actual cyber attacks. On the other hand, vulnerability assessments are a more static analysis of potential weaknesses.
• The value of an outsider's perspective: As Nassim Nicholas Taleb posits in his theory of "Black Swan", we are often blind to our own shortcomings. An external penetration testing firm provides the invaluable advantage of an outside perspective, unencumbered by internal biases or assumptions.
• Communication is crucial: While the technical prowess of penetration testers is a given, their ability to communicate effectively is equally important. The testers must be able to clearly articulate their findings, the risks they pose, and potential avenues for remediation.
• Penetration testing is cost-effective: While the upfront cost of penetration testing may seem steep, the potential cost of a security breach far outweighs it. According to a study by the Ponemon Institute, the average cost of a data breach in 2020 was $3.86 million.
• The human factor: Penetration testing is not exclusively a question of technology; humans are invariably the weakest link. Hence, penetration tests that incorporate social engineering tactics can provide a more holistic overview of your organization’s vulnerabilities.

Thus, while penetration testing is an invaluable tool in the cybersecurity arsenal, it is not a panacea. A comprehensive and effective cybersecurity strategy necessitates a multi-faceted approach, and penetration testing is but one facet, albeit a crucial one. The journey towards robust cybersecurity is long and winding, and I hope that these insights illuminate your path a little.
