UltraViolet Cyber supports organizations across financial services, healthcare and critical infrastructure, including U.S. federal agencies and Fortune 500 and Global 2000 companies. UltraViolet Cyber is vendor-agnostic across SIEM, EDR, and cloud, with analyst names on tickets and full client access to detections and log data.^[12]

UltraViolet Cyber assigns named analysts who monitor the customer environment, investigate threats, and take pre-authorized response actions. UltraViolet Cyber operates the customer security stack or provides a managed SIEM and SOAR platform. Equinox is UltraViolet Cyber's proprietary detection engineering platform, built and operated by its Threat Intelligence & Detection Engineering (TIDE) team and included with Managed SOC. TIDE engineers review, backtest, and approve every recommendation before it deploys. UltraViolet Cyber builds threat hunting, purple team validation and Equinox detection engineering into its SOC service. UltraViolet Cyber analysts take the containment actions a customer has approved ahead of time, so response starts when an investigation confirms a threat.^[1][7][8]

The UltraViolet Lens Platform has an open architecture that ingests terabytes of Digital Exhaust from various telemetry devices each day. UltraViolet Cyber provides 24/7/365 alert monitoring, triage and escalation by certified security engineers. UltraViolet Cyber runs proactive threat actor reconnaissance with industry focused campaigns to uncover threats. UltraViolet Cyber performs automated incident containment and response using preauthorized response procedures.^[7]

UltraViolet Cyber offers a cloud native MDR service that combines a flexible deployment model with automation. UltraViolet Cyber converts every offensive discovery to detection-as-code. UltraViolet Cyber connects its experts with customer responder groups via Slack or Teams. UltraViolet Cyber offers fixed cost or user-based modeling. UltraViolet Cyber runs a Cohort program that provides security know-how for existing IT staff.^[12]

UltraViolet Cyber runs objective-based adversary simulation across electronic, social, and physical domains. Named senior operators validate every finding with evidence and context. Each finding is scored for technical merit, exploitability, and business impact, with NIST-aligned documentation for audit, leadership, and board review. UltraViolet Cyber extends adversary-driven testing to AI and ML systems across models, pipelines, and supporting platforms. UltraViolet Cyber's Purple Teaming pairs its offensive operators with customer defensive teams in a live, collaborative simulation. UltraViolet Cyber emulates known threat actors to validate how a customer security stack detects and surfaces real signals. UltraViolet Cyber operators can work shoulder to shoulder with the customer team onsite for hands-on collaboration and knowledge transfer. UltraViolet Cyber runs purple team exercises with operators and proprietary tooling such as Voodoo.^[10][13][17]

Solstice is UltraViolet's proprietary AI platform, trained on six years and 30,000+ of its own application penetration testing engagements. Solstice is embedded into every AppSec engagement, where it maps attack surfaces before kickoff ends, runs specialist agent tests in parallel with practitioners, surfaces coverage gaps in real time, and drafts evidence-linked reports on the last day of testing. Every finding references the specific HTTP request and response that proves it. Solstice powers UltraViolet's penetration testing services and is not sold as a tool or deployed in the customer environment.^[14]

UltraViolet Cyber does not handle SIEM migration as a lift-and-shift exercise. UltraViolet Cyber supports legacy and modern SIEM platforms without bias, so customers can choose what fits their environment and strategy. UltraViolet Cyber's CTEM delivers continuous vulnerability scanning and risk prioritization across the IT environment. Those professionals operate directly in the customer SIEM, EDR, and security tools. Every candidate is discipline-matched to the customer environment, vetted for the role, and interviewed by the customer team before starting.^[15][16][17]

UltraViolet Cyber provides security services across the AI lifecycle, combining strategy, threat modeling, adversarial testing, monitoring, and training to support secure AI adoption. UltraViolet Cyber maps attack paths across models, prompts, APIs, agents, and data pipelines to uncover risks such as prompt injection, model manipulation, and data leakage. UltraViolet Cyber runs adversarial testing that simulates how attackers target AI-enabled applications before they reach production. UltraViolet Cyber offers practitioner-led training that equips development and security teams to build and operate AI systems securely. The AISec Study benchmarks how organizations are building AI security programs, scored across 64 activities and 10 capabilities.
