The Real-World Threats Organizations Face
Introduction
Most people think surveillance only happens in spy movies.
But in reality, the most common surveillance threats happen in normal workplaces, meeting rooms, offices, boardrooms, and vehicles.
And they aren’t theoretical.
They’re happening every day.
If your organization discusses strategy, money, intellectual property, emerging product designs, mergers, legal cases, or negotiations, someone could benefit from hearing those conversations.
That’s why Technical Surveillance Countermeasures (TSCM) exist.
Let’s break down the 4 real-world threat categories we encounter most often during professional sweeps:
🔊 1. Hidden Audio Devices
Small microphones are now:
Cheaper
Smaller
Easier to hide
And easier to buy than ever before
We find audio devices:
Inside office chairs
Inside light fixtures
In pens and USB chargers
Hidden behind drywall
Some record and store audio.
Some transmit live in real time.
These devices are intentionally designed to blend in.
This is why “looking around the room” is not a security strategy.
📹 2. Covert Video Surveillance
Micro-cameras today are:
Capable of HD resolution
And often indistinguishable from everyday objects
Common disguises we encounter:
Smoke detectors
Screw heads
Wi-Fi extenders
Power bricks
Wall or desk décor
What gets recorded isn’t always “conversation.”
Often, it’s:
Whiteboard notes
Laptop screens
Badge access
Meeting schedules
In other words: the context behind your decisions.
📡 3. Wireless & Network-Based Devices
Not all devices record.
Some devices transmit.
This is where threats become harder to detect without specialized equipment.
We regularly detect:
Bluetooth transmitters
Wi-Fi transmitters
Cellular-connected devices
GPS trackers on vehicles
These devices hide inside your network noise.
To the untrained eye, it looks like “just another Wi-Fi signal.”
To us, it’s a red flag.
🧍♂️ 4. Insider-Enabled Compromise
This is the hardest to talk about — because it doesn’t require a hacker.
It requires access.
Insiders (employees, contractors, vendors, cleaning crews, maintenance staff) may:
Leak information intentionally
Be bribed
Be socially engineered
Or simply be unaware they are enabling access
This is why trust is not a security protocol.
Verification is.
So what’s the risk?
Surveillance is almost never random.
It is purpose-driven and usually financially motivated.
Real-world consequences include:
Lost contracts
Lost patent opportunities
Compromised negotiations
Lawsuits
Erosion of reputation and trust
These are risks that most businesses never recover from.
This is why TSCM is not just “finding bugs.”
It is:
Adversarial thinking
Forensic inspection
RF data analysis
Facility vulnerability assessment
Policy hardening
Insider risk evaluation
The tools matter.
But the operator matters more.
At CastNet, we’ve been on the other side of surveillance.
As former FBI Technically Trained Agents, we didn’t just learn how to detect devices —
we installed them for federal investigations.
Which means:
We know the methods.
We know the hiding places.
We know the behavior patterns.
And we know how to stop them.
If your business handles sensitive information…
This isn’t paranoia.
This is modern security.
