About The Customer

Calligo is a data service provider committed to delivering reliable and secure services to its customers. The company places a high priority on safeguarding sensitive customer data. However, during the rapid transition to remote working in 2020, Calligo found itself targeted by an increasing number of sophisticated phishing emails that its existing security tools were unable to stop. This led to the company seeking a more robust and effective solution to protect its digital ecosystem and keep its sensitive data safe.

The Challenge

Calligo, a data service provider, was facing a significant challenge in safeguarding sensitive customer data from phishing attacks and spoofing emails. The situation was exacerbated during the rapid transition to remote working in 2020, which saw an increase in the number of sophisticated phishing emails that their existing security tools were unable to stop. These included fake invoices sent to the accounting team. While their legacy tools were effective at stopping spam and other common threats, they failed to catch the novel attacks increasingly targeting the workforce. Calligo's Chief Information Security Officer, Mark Herridge, acknowledged that their existing email protection had gaps, particularly in dealing with phishing and spoof messaging. The company needed an email security solution that could provide better visibility across their vast digital ecosystem and stop advanced email-borne threats that would otherwise go unnoticed.

The Solution

Calligo decided to extend Darktrace's coverage to the email realm with Antigena Email, an autonomous AI cyber security solution. Antigena Email takes surgical action to contain in-progress threats within seconds. It works by learning what is 'normal' for every user and detects anomalous emails that fall outside this learned 'pattern of life'. This contextual understanding of all email traffic allows the AI to spot advanced attacks that signature-based tools miss. When cyber-attacks arise, Darktrace takes autonomous and proportionate action to stop the threat while allowing business functions to continue as usual. Antigena Email was installed in five minutes, cloud-delivered, and effective within hours, protecting Calligo's workforce from a range of email threats. In addition to protecting against novel and sophisticated email threats, Darktrace's Cyber AI Analyst helped augment the security team at Calligo by launching autonomous investigations at machine speed into every security event.

Operational Impact

The implementation of Darktrace's Antigena Email and Cyber AI Analyst has resulted in a substantial improvement in Calligo's email environment. The AI-driven solution has not only helped in stopping advanced email-borne threats but also provided better visibility across their vast digital ecosystem. The autonomous investigations launched by Cyber AI Analyst have added substantial value to Calligo's security stack, especially in its ability to launch on-demand investigations and query SaaS data at any time. The intelligence provided by the AI Analyst is clear and actionable, making it a valuable tool even for the newest and most inexperienced members of the security team.
