Why Open Source Intelligence with Bridewell?

Bridewell’s OSINT service uses a complete range of information gathering techniques to identify potential risks, vulnerabilities and weaknesses that could be exploited by attackers. Once identified, our consultants can work with you to prioritize them and either isolate or remove the sensitive data before an attacker can utilize it.  

This service is a valuable component of wider penetration testing activities, such as Red Team exercises, and helps simulate a real-life cybersecurity attack on an organization's infrastructure, wireless networks, applications or mobile devices.

Bridewell needs minimal involvement from your organization to complete the assessment, reducing the burden on in-house teams.

Each assessment delivered by out penetration testing team is customized to address specific security concerns within your organization.

Bridewell works with organizations across highly regulated and critical industries, providing our pen testers with a deep understanding of the risks and challenges they commonly face.

Our penetration testing team holds accreditations from the OSCP, Zeropoint Security CRTOs, CREST, are Tiger-certified and hold Certified Cyber Security Consultancy status with the National Cyber Security Centre (NCSC). 

Key Challenges Addressed

Many information sources detail valuable data via OSINT such as usernames, job titles, contact details, and recruitment information that can be used to build a detailed picture of an organization and their people.

This can be used by malicious actors to target their attack and improve their likelihood of success. To address this, organizations need to understand where information is leaking and how it could be used against them. 

However, searching for OSINT can return overwhelming amounts of data, much of which might not prove useful. Instead, organizations need a clear strategy in place for acquiring accurate information that will help them focus their efforts. Given that this requires experience searching for OSINT and a strong understanding of how it can be used, it is uncommon to find these capabilities within most organizations. 


Open Source Intelligence

How it Works

Bridewell uses a combination of active, passive and semi-passive gathering to collect as much information as possible about your organization from publicly available sources. In particular, our team searches for:

  • Physical security measures for the location
  • Infrastructure and networking detail
  • Full DNS listings of all associated assets
  • Netblock owners (whois data) and email records (MX + mail address structure).
  • Any other information relating to organizations and employees which could potentially be used in future exploits
  • Information from previous breaches and any passwords associated with your organization's accounts

The information gathered during this stage is often used to inform wider penetrating assessments from our team, which can vary depending on the specific requirements of your organization. Our consultants also use these insights to guide your organization on how they can remove this information or take actions to mitigate the risk posed by it. 

NSCS Certified Services


The term ‘open source’ refers to publicly available information. Open Source Intelligence, OSINT for short, refers to data and information that’s been collected from numerous sources to be used for intelligence purposes. 

OSINT is primarily used in law enforcement and business intelligence, but is also valuable and widely-used by security professionals to help them carry out their services, assessments and security testing procedures.

While Open Source Intelligence does derive a great deal of information from publicly available sources, ranging from social media data to online publications, there are concerns for its legitimacy and accuracy.
