Perception Update - Version 2.5.9

Version 2.5.9 adds a number of new features to Perception, including features to increase security, system performance, and usability issues.

To start, Perception now supports communicating over HTTPS with the UI, and allows the import of certificates.  Although communication over a secure VPN was already fully encrypted, the addition of standard web-security measures increases the security of the system as a whole.

Performance is always a priority for us at Perception, and in this update we continue to improve system performance.  We’ve changed the way our databases are structured, which means queries run faster and less disk space is required, we’ve also squashed a bug where very large databases were causing system performance issues.  Likewise, the cache of SMB data was causing some sensors to use too much memory, and this issue has been resolved with no effect on the detection performance of SMB-based behavioural identification.

Self-managed users will also benefit from the latest improvements to the user interface, including a number of smaller fixes that should improve usability.  You can now delete swimlanes in KnowledgeBase if they are no longer needed, and some ForensicAI alerts have been provided with more detailed microcontrol information, meaning the alert can be triaged better without even opening the alert at all.


A full list of updates are below:

  • Added support for HTTPS connections to the UI including certificate import.

  • Significantly enhanced database format giving improvements in query performance and disk space requirements.

  • Fixes for database performance issues when accessing very large databases.

  • Added ability to delete swimlanes from KnowledgeBase Incident Builder.

  • Improvements to SMB memory use to address issues with overloaded sensors.

  • Various UI fixes and improvements.

  • Enhancements to ForensicAI Alerts to give more detailed Microcontrol information and more accurate scoring.

  • Fix for Exceptions not matching on hostnames correctly.


This update will be pushed to all managed customers at the pre-agreed upgrade time.  Self-monitored customers can update their own systems using the software upgrade processes.  If you have any further questions about this upgrade please contact us at

Frost & Sullivan Recognises Perception as Most Innovative New Cyber Security Software

Frost & Sullivan has recognised Perception Cyber Security with its 2017 New Product Innovation Award, describing it as a "game-changing cyber security solution."

Perception was originally developed by Chemring Technology Solutions for the UK Ministry of Defence. Complementing existing computer network security systems, such as firewalls, intrusion detection systems, and antivirus software, Perception is a behavioural analysis system with no rigid rules-based architecture.

Dhiraj Badgujar, Analyst at Frost & Sullivan, said: "The increasing complexity of network security is becoming difficult for businesses to manage, leading to mistakes or gaps for attackers to exploit. With its deep learning capability and the ability to adapt based on changing network behaviours, Perception will enable enterprises to identify future advanced threats before they emerge."

The major differentiating factors of Perception are its ability to identify malicious activity without requiring prior knowledge of the threat, as well as alerting the user to potential vulnerabilities so they can be resolved before an attacker exploits them. This makes it more difficult for malware to evade detection and easier for analysts to proactively detect network vulnerabilities and user error.

As well as detecting threats and vulnerabilities as they happen, Perception uses artificial intelligence (AI) to intelligently interlink network events across months, weeks, and minutes, enabling large-volume data pattern analysis. This significantly improves "low and slow" threat detection capabilities, in addition to providing a low false alarm rate. Perception also detects the slow, unauthorised external extraction of information from the network, even when sophisticated obfuscation techniques are used.

Daniel Driver, Head of Perception Cyber Security, said: "Based on declassified work for national security agencies, Perception takes the fight against cybercrime to a new level. An award from the respected international analyst firm Frost & Sullivan's gives us an unbiased, third-party stamp of approval. The Perception development team truly deserved to be recognised in this way as it proves to us that we have created something truly unique in identifying advanced cyber threats."

For the New Product Innovation Award, Frost & Sullivan analysts followed a 10-step evaluation process to assess Perception's fit against best practice criteria, focusing on two key factors - New Product Attributes and Customer Impact.
