Private investigation Agency
Northwall OSNIT & Surveillance logo



There are many reasons why you might want to hire Northwall, from covert background checks of an individual or relative to full security penetration testing of corporate enterprises and high net worth individuals. We use a broad range of skills and techniques to obtain the information needed to assess any threat to yourself or your company and recommend measures to manage the risks.

The UK government will soon publish the "Protect Duty" guidelines which are currently going through the consultation phase. We provide a high quality consultancy service in this area and can help clients to protect their businesses against terrorist attack.

Social media hate crime is another area where we provide consultancy services.  Using open source intelligence (OSINT) we are often able to identify and locate offenders where the Police Service cannot due to lack of resources and limitations regarding compliance with the Regulations of Investigatory Powers Act.

Our first concern is client safety and anonymity.  We are totally discreet and will never allow our clients to be identified. We work hard for our clients and go the extra mile to get the results they require.   

Our aim is provide our clients with peace of mind by providing detailed and evidenced information; and recommending practical measures to reduce any impacts.
