Why Traditional TPRM is Outdated: The Failure of Security Silos

Outdated TPRM keeps cyber security teams in silos. Learn how collaborative third‑party risk management strengthens supply chain security and stops wasted effort.

Cyber security is currently the only industry where every organisation tries to solve the exact same problem, at the exact same time, in total isolation. While threat actors operate as highly efficient, collaborative networks, the defenders are trapped in silos, duplicating effort and wasting resources on a massive scale.

The Problem: A Fragmented Approach to a Global Threat

One of the most glaring shortcomings of modern TPRM is that it is conducted in a vacuum. The lack of a standardised assessment framework and a culture of secrecy prevents organisations from sharing the burden of security, leading to a system that is as inefficient as it is ineffective.

Key Reasons Why Security Silos Represent a Problem:

  • Massive Duplication of Effort: A single mid-sized supplier may be forced to fill out 500 nearly identical security questionnaires for 500 different clients. This "administrative tax" drains the supplier’s security budget away from actual defence and toward repetitive paperwork.

  • Inconsistent Standards: Without a unified framework, every organisation creates its own definition of "good" security. This fragmentation confuses suppliers and makes it impossible to compare risk levels across a diverse supply chain.

  • The "Defender’s Disadvantage": Attackers share tools, techniques, and target data in real-time. By contrast, defenders rarely share insights about supplier vulnerabilities or breach patterns due to legal concerns or competitive friction, giving the "home field advantage" to the adversary.

  • Scalability Bottlenecks: Assessing every supplier individually is a linear solution to an exponential problem. As digital ecosystems grow, the manual, siloed approach to TPRM becomes physically impossible to maintain, leading to critical suppliers being ignored or rushed.

  • Wasted Intelligence: When one organisation discovers a security flaw in a common supplier, that knowledge remains locked within their silo. Their peers—who share the same supplier—remain vulnerable to the exact same threat until they happen to discover it themselves.

  • Stifled Collective Defence: The current model prioritises "protecting my own organisation" over "hardening the network" for mutual benefit. This isolationist strategy fails to recognise that in a hyper-connected economy, a weakness anywhere in the ecosystem eventually becomes a threat to everyone.
