TSCM Question: Is Dip Sampling Enough to Protect Against Risks?
TSCM Question: Is Dip Sampling Enough to Protect Against Risks?
A frequently asked TSCM question, posed by clients; “Is dip sampling sufficient to cover my risk?” Let us address this concern head-on.
Recently, we became aware of a so-called ‘high-level’ TSCM service provider who regularly conducts dip sampling instead of performing full TSCM surveys. This provider claims to be an authority in Technical Surveillance Counter-Measures, but their methods have shocked the global TSCM teams we have trained. So, what exactly is wrong with their approach?
What Is Dip Sampling in TSCM, and Why Is It Problematic?
This provider is selling a service they call a ‘TSCM survey,’ in which they randomly inspect just 10% of the area of concern. Yes, only 10%! Let’s break that down:
Areas at Risk of Technical Surveillance:
- How it should be surveyed: A complete, thorough inspection of 100% of the space.

- What a 10% dip sample secures: Minimal coverage, leaving 90% of the area unchecked and vulnerable.

TSCM Question, But, Is Dip Sampling Acceptable In Other Areas of Security?
Would you accept this standard for your organisation’s network security or physical security? Of course not. Yet, this is the level of risk some TSCM providers impose on unsuspecting clients.
Network at Risk:

- How it should be protected: Comprehensive monitoring and safeguarding.

- What a 10% dip sample achieves: A fraction of protection, leaving significant vulnerabilities.

TSCM Question – How Can This Happen?
You might be wondering, “How do these providers get away with this?” Or worse, “Have I unknowingly hired such a service provider?” If the latter is true, you may have fallen victim to a provider offering a service that is simply unfit for purpose.
