Operators and scale-ups alike face sophisticated attackers and tightening regulation, but not all can justify a permanent senior security team. The interim or fractional CISO model has surged to meet that need. “You do not always need a permanent thirty-person team,” says Professor Kai London, a senior CISO who takes on these mandates. “Sometimes you need the right senior hands, for a defined period, to set the strategy, fix the worst gaps and leave something the board can run.”

“The risk and the regulation do not scale down. The fractional model is how organisations get board-grade leadership without the delay and cost of a permanent hire.”

Same obligations, leaner teams

“A determined attacker and a demanding regulator treat a mid-sized operator the same as a giant,” London notes. Many carry large obligations on modest frames.

What it delivers

Senior leadership on a part-time or time-boxed basis, starting from the outcome the organisation needs — a deadline, a stabilisation, an incident, a due-diligence review. “Senior judgement from day one, without the ramp-up of building a team,” he says.

Speed and expertise

A permanent search can take most of a year; the interim model compresses that to days, and gives organisations access to frontier expertise — telecoms security, AI governance, post-quantum readiness — they could not justify full-time. A good engagement builds lasting capability, not dependency.

For a sector where organisations of every size share the same threats, London's message is encouraging: board-grade cyber leadership is now within reach — senior hands, on the mandate in front of you, for exactly as long as you need them.

Post-Quantum Cryptography and the Future of Secure Communications: Professor Kai London Explains

Credit: professorkailondon.com The confidentiality of communications rests on cryptography — and that cryptography faces an eventual reckoning with quantum computing. For telecoms and secure-communications providers, Professor Kai London , a senior CISO, argues preparation must begin now. “Communications that must stay confidential for years are already exposed to the harvest-now-decrypt-later threat,” he says. “Adversaries capture encrypted traffic today to decrypt it once quantum computers mature. For anything that must remain secret over time, the clock has already started.” Why communications are especially exposed London notes that intercepted communications have long shelf lives — diplomatic, commercial and personal data that remains sensitive for years. “If it must stay confidential into the next decade, it is already at risk,” he says. The standards are here Concrete po...

The Invisible Airborne Perimeter: Professor Kai London on Wireless Threats and Nation-State Actors

Credit: professorkailondon.com Wireless networks create a perimeter most organisations never defend because they cannot see it — and for critical operators, sophisticated adversaries have learned to exploit it. “There is an airborne perimeter around every site: the radio space an attacker can reach without touching a wire,” says Professor Kai London , a senior CISO. “Nation-state actors have demonstrated advanced capabilities against exactly this surface.” “No malware, no perimeter breach, no trace — just an adversary impersonating a network your systems trust. For critical operators, that is a strategic risk.” The evil-twin and beyond London describes rogue access points that mimic legitimate networks and harvest credentials, and notes that capable adversaries go further — targeting telecoms and wireless infrastructure directly. “The most advanced actors treat the airwav...
