For law firms, trust isn’t essential. It’s foundational. Protecting highly sensitive client information is a core responsibility, made more challenging by determined threat actors and an ever-evolving global regulatory landscape. To maintain client confidence and meet compliance requirements, firms must take a proactive, resilient approach to cybersecurity.
That’s why one of the world’s largest and most prestigious law firms chose Cyderes and its Managed Detection & Response solution to improve their cybersecurity posture.
Over the years, the law firm faced several challenges impacting its operations:
Indifferent service
Previous managed security providers didn’t operate at speed or provide sufficient guidance on maximizing existing technology defense investments. This left the firm to continuously tune and configure defenses rather than focusing on strategic improvements which impacted team morale.
High costs
The cost of the firm’s security information and event management (SIEM) solution was tied to data volume – the more volume, the higher the cost. This meant that the firm had to decide between better data-driven security or cost management.
Poor scability
At that time, the firm was in a phase of significant growth, especially in the U.S. However, as the firm expanded, its cybersecurity challenges also increased alongside evolving technology investments. To manage costs, the firm had to throttle the data fed into the platform, which ultimately undermined the benefits of a data-driven security program.
The firm began to search for other security partners to address its primary challenges.
“We provide world-class service to our clients,” the law firm’s CISO explained. “So we expect world-class service from our security providers.”
The firm began evaluating potential replacement technologies and partners, shortlisting just two options. As it turned out, the decision to select Cyderes was easy.
“We were already familiar with Cyderes,” said the CISO. “They knew our business from previous years and we knew the quality of their service and their people.”
A decisive factor in the firm’s choice was Cyderes’ cloud-native Threat Detection, Investigation, and Response (TDIR) platform. Built to ingest and correlate petabytes of telemetry, the platform delivers actionable threat intelligence with sub-second search. Its advanced detection engine continuously updates with new rules and threat indicators, helping the firm stay ahead of emerging threats.
Cyderes' Managed Detection & Response (MDR) delivers real-time attack visualization, clearly showing who did what and when across every entity involved in an incident. Patented technology automatically correlates related alerts into a single, threat-centric case, enabling faster investigations and more confident response.
Built-in automation and ready-to-run use cases for common threats such as phishing and ransomware allow the firm to respond in minutes while gaining greater visibility into its security posture. Customizable orchestration playbooks, enhanced by generative AI–powered context and response guidance, help the team act decisively and stay ahead of what’s next.
Since the firm couldn’t risk downtime, the migration to Cyderes' MDR took place in a live environment. The new solution ran in parallel with the incumbent platform until the transition was complete, ensuring continuity throughout the six-month crossover. This approach preserved trust, protected sensitive client data, and maintained compliance with stringent global regulatory requirements every step of the way.
A key contribution from the Cyderes team was its expertise in optimizing and rationalizing the new environment. Cyderes identified duplicate use cases, reduced redundant alerts, and eliminated log feeds that didn’t support meaningful detections. This ensured the firm retained only the log sources that added clear value to the service.
Beyond its extensive library of out-of-the-box and custom detections, Cyderes rebuilt the firm’s use case–specific logic within the new system. Drawing on insights from its broad customer base, the team also introduced new rules and refined existing ones to strengthen detection coverage and improve signal quality.
“We didn’t have enough rules in the old world,” the firm’s CISO explained. “Cyderes was able to offer us a bigger set of rules, so we asked them to show us what we should be looking at, and they did a great job. The proactive part of the relationship is really valuable to us.”
With the transition complete, the firm shifted focus to outcomes. Cyderes built dashboards to measure performance across multiple KPIs, giving the firm clear visibility into results. These dashboards also enable continuous tuning of detection rules, improving accuracy and effectiveness over time.
"Our strategy in working with Cyderes was to get our costs down, get a better, more scalable service, and be important,” the CISO reiterates. “And we’ve ticked all those boxes."
They added that the firm’s previous platform took years to reach a level of maturity that Cyderes achieved in just six months. The next phase will introduce generative AI capabilities, enabling the team to engage with Cyderes through context-aware, AI-powered chat — including the ability to create detections and playbooks with greater speed and precision.
By partnering with Cyderes, the firm transformed its cybersecurity program into a scalable, cost-efficient operation built for long-term resilience. Cyderes MDR delivered the visibility, speed, and proactive guidance needed to protect sensitive client data while supporting growth and compliance. More than a technology upgrade, the engagement established a trusted partnership rooted in service, accountability, and continuous improvement. With a stronger security foundation in place and a clear roadmap that includes generative AI–driven capabilities, the firm is well positioned to stay ahead of evolving threats while preserving the trust that defines its profession.
