Security Risk Assessments

DeepSeas evaluates assets, scenarios, vulnerabilities, impacts, likelihood, and existing controls to create a documented risk assessment and prioritized treatment plan.

Compromise Assessment

Experts examine endpoint, identity, network, cloud, email, and other telemetry for evidence of current or historical intrusion, then document findings and immediate actions.

Penetration Testing

Ethical hackers conduct controlled tests and attack simulations across systems, applications, infrastructure, and processes to expose weaknesses before malicious actors exploit them.

Cloud Penetration Testing

Manual testing examines cloud identity, permissions, configurations, exposed services, APIs, secrets, logging, and boundaries between environments to uncover realistic attack paths.

Vulnerability Management

DeepSeas discovers and assesses vulnerabilities, prioritizes findings by exploitability and asset criticality, tracks remediation, and reports whether overall exposure is reducing.

Governance Risk Compliance

GRC services connect risk management, control development, evidence collection, continuous monitoring, and reporting to support audit and regulatory requirements.

Actionable Risk Insight

Turn Cyber Risk Into Clear Priorities

DeepSeas 365 Security Risk Assessment moves beyond a catalog of observations. The engagement examines what an attacker could reach, how controls and processes perform, and which risks deserve attention first. Stakeholder interviews, asset inventory development, risk workshops, scenario selection, and formal documentation produce a clear report and treatment plan. Leaders gain a practical basis for investment, governance, compliance, and security improvement decisions.
