Counter Surveillance

Diligent: Counter Surveillance At Home Or At Work

Covert Security Team

Protective Surveillance measures involves a team blending into the environment by disguising themselves as colleagues or staff. This often allows them to spot hostile surveillance as they do not know that they are there.

Overt Security Team

A close protection team or overt security will keep the private client and their family safe by being there at all times. This type of personal security has the advantage of being a very good deterrent.

Electronic Security

Installing overt CCTV cameras will allow you to monitor sensitive areas and act as a deterrent. Covert CCTV will catch hostile persons in the act.

Engaging a private investigator as due diligence will ensure that you will not be violating any privacy or data protection laws with recording devices.



Electronic alarms and electric gates in the right places are a fantastic security measure. Consulting an experienced surveillance agent will allow you to place these where you are most vulnerable. The best way to stop you being put under surveillance is to consult someone who conducts surveillance for a living.

Such activities make it tricky for any third parties to put you under surveillance. It also acts very much as a deterrent. Knowing someone is surveillance aware and has counter surveillance measures in place can often be enough for any third party threat to stay away! 

Bug Sweeps

Bug sweeping is the term given to checking an area for listening devices or cameras. By their very nature they will be very difficult to detect and there are two things you need to find them.

Firstly there is bespoke technical equipment which is used to detect devices in your location. These include radio frequency detectors which can find transmitters, nonlinear junction detector for semiconductor electronics and reflection detectors to find camera lenses to name but a few.

Secondly it is best to engage a private investigator to search for the devices. Again the best person to find something hidden is someone who's job it is to hide them in the first place.

Background Checks

Background checking staff and contractors is an excellent way to spot fake identities or individuals with suspicious backstories.

Building Alterations

Planting shrubbery or tree lines in the right place will obscure line of sight but in the wrong place might allow concealment.

Net curtains, blinds or keeping doors closed may sound simple but it will block views. These days it is possible to spy on a computer screen from miles away or from a higher vantage point with drones.

Diligent: Secure Your Computers And Electronic Devices

The threat of being hacked online is constant, however if you are under hostile surveillance then the risk increases exponentially.

There are several steps that you should take to safeguard your data:

• Install and use anti malware or spyware software.
• This is software specifically designed to clean your computer from programs that hackers use to access your system or to retrieve data. 
• Often spyware or malware is installed through websites but the most effective and damaging ones can be installed physically should someone have access to your system or be targeting your network.
• An agent can advise you on the best software to use.
• Password lock your computer when you are not there or have the lock on a timer.
  Anyone trying to get access to your computer is going to find it very difficult to get past a password screen. Often potential hackers will wait for a person to leave their computer unattended and quickly gain access or lower security so they can gain access other ways.
• Use a robust and up to date firewall
  This is software which is designed to keep unwanted outside parties from accessing your computer.

• Install anti-virus software and set up regular virus scans.
  

Diligent: Counter Surveillance On The Move

Any surveillance agent will have a number of ways to track you on the move which will often involve using an electrical tracking device.

A professional investigator will know where to place these devices so that they will not be found. You can then be tracked potentially anywhere in the world.

It would take a well trained and experienced agent to know the areas where these GPS tracker devices will be secreted and have hardware that can detect it.

Not all measures are electronic and you should not underestimate the power of old fashioned discretion.



• Make yourself harder to recognise with clothing, hats or glasses. Try changing some of your clothes from when you leave your house or work. 
• Vary your routines and journey paths. This will make it difficult for hostile surveillance agents to pick you up.
• Do not share your whereabouts or plans with people. This can be someone at work or even on social media.
