WHY ULTRAVIOLET FOR FINANCIAL SERVICES

Turn Offensive Findings into Defensive Action

UltraViolet unites offense and defense so each informs the other. Your teams use red team findings to guide blue team action, protect payment systems from real-world threats, and demonstrate how well those defenses perform.

Strengthen Defenses Against Real-World Tradecraft

Find attack paths across banking applications, payment APIs, AI, and infrastructure. Red team findings sharpen SOC detections and playbooks.

Protect Critical Financial Operations

24/7 monitoring and response, supported by proactive threat hunting, helps your team detect and contain threats earlier. 

Prove How Your Defenses Perform Under Pressure

CREST-accredited testing and purple team validation show your board and examiners what was tested, what held, and what needs attention.

Modernizing SIEM Operations Without Disrupting Detection

Read the Full Case Study

A Phased SIEM Migration Built for Scale and Continuity

Financial Services

A global digital banking and lending technology provider needed to migrate from an SIEM processing more than 70 TB each day without disrupting security operations. UltraViolet led a phased migration to SentinelOne, modernizing detections and preserving continuity throughout the transition.

 

The Challenge

  • The existing SIEM processed more than 70 TB of data each day, driving up licensing and infrastructure costs.
  • More than 4,000 saved searches, alerts, and dashboards needed to be accounted for before the migration could begin.
  • Security operations had to continue throughout the transition, leaving little room for downtime or gaps in coverage.
  • Detection logic developed over time needed to be carefully preserved, rebuilt, and validated in the new platform.
  • As the environment grew, the legacy platform became harder to scale and less responsive for day-to-day security operations.

The Solution

  • UltraViolet developed a phased migration plan that let the organization modernize its SIEM without disrupting security operations.
  • Parallel data ingestion gave the team time to validate data quality and performance before moving critical workloads into production.
  • More than 4,000 searches, alerts, and dashboards were reviewed and rebuilt to work effectively in the new SentinelOne environment.
  • Detection logic was refined during the migration to improve performance while preserving the security use cases the team relied on.
  • Structured testing, validation, and stakeholder coordination helped keep operations running from the first migration phase through final cutover.

Grounded in Regulations, Frameworks, and Standards That Make Security Measurable 

We map engagement findings and defensive coverage to established regulations, frameworks, and standards. This gives your team a consistent way to measure exposure, validate progress, evaluate AI risk, and communicate resilience to boards, regulators, and examiners.

USE CASES WE SOLVE

Aligned to Your Priorities

Start with your highest-priority risks, then align testing, detection, response, and validation with your environment, release schedule, and compliance deadlines. Give your security team, developers, and SOC practical next steps to protect customer data, secure transactions, and keep banking and payment services running.

Find Design Flaws Before Application are Built

Threat modeling and secure design reviews assess new platforms and features before code ships, so weaknesses are fixed in design rather than in production.

Frequently Asked Questions

We’re deploying AI in customer-facing and internal systems. How do you test it?

We assess how attackers could exploit your AI systems and the applications, data, and infrastructure connected to them. Depending on your environment, testing combines attack surface discovery, cloud configuration review, and adversarial testing of models, agents, and orchestration layers, mapped to MITRE ATLAS.

Findings help your security and development teams prioritize fixes and inform AI governance decisions. Where we also provide detection and response, we use those findings to guide threat hunting.
