About No Safe Harbor

Stories of massive data breaches litter the 24-hour news day headlines. A who’s who of banks, retailers, law firms, and healthcare organizations are affected by hackers and cybercrime syndicates. These companies, however, are often those with the most sophisticated technological systems in place, designed to stop crime before it starts. So how and why do cybercriminals continue to breach their ranks? And how can smaller companies with fewer resources at hand protect themselves?

The story of digital crime told by cyber security expert Mark Sangster, VP of Industry Security Strategies at eSentire, is one that hasn't been told before: one in which the key to changing the locks isn't in our computers, but in our corporate culture. Sangster deftly weaves together real-life criminal cases in a thrilling narrative that illustrates the human complexities behind the scenes that can directly result in an open door to threats. Within a security context, deep social engineering is the newest and biggest means of breaching our systems. Sangster shows readers that, in a world where the notion of truth is evaporating, organizations need to shift the security discussion away from technology gates alone toward a focus on leadership, team behaviors, and mutual support.

What the Experts Are Saying About No Safe Harbor

ALM Cybersecurity Law

Mark provides a real wake-up call to law firms and companies of all sizes, especially to those that think they are too small or inconsequential to be the target of cyber crime. He draws from his expertise and experience to break down the misconceptions of cybersecurity and uses real life examples to demonstrate the myriad ways cyber criminals can attack. Likening cyber viruses to the unprecedented global pandemic, “No Safe Harbor” explains that cybersecurity has to become part of strategic planning; we can no longer just react to security issues, we have to have a mindset of protection.

This is a ‘must read’ for any aspiring business leader.

Mark Sangster’s advice could not have arrived at a more propitious moment, as the work paradigm changes to remote information systems access as a default rather than an exception. The book reads like a collection of short stories, all revolving around a central theme: Cybersecurity is a business risk and a people challenge and the approach to those people should be made, as Mark does so well, by appeals to common sense and documented in easy-to-understand frameworks. This book should be essential reading for senior management and corporate directors.
