DeepSeas provides continuous detection and response across cloud, identity, endpoint, network, email, SaaS, and operational technology environments, using existing security tools where possible.
DeepSeas operates detection, tuning, investigation, and response inside your existing SIEM or provides SIEM capabilities with ingestion and storage included.
Continuously identify external assets, exposed cloud resources, leaked credentials, vulnerabilities, and attack paths, then prioritize findings by exploitability and business impact.
Manual cloud penetration testing examines identity, access, configuration, exposed services, APIs, secrets, logging, and boundaries between accounts and environments.
Discover vulnerabilities, prioritize them using threat intelligence and asset criticality, track remediation, and report whether overall exposure is decreasing.
Experienced advisors help leaders make defensible decisions about cloud security strategy, governance, technology, compliance, risk, and operating models.
Managed cloud security brings detection, investigation, testing, and advisory together so security teams can focus on the risks that matter most. DeepSeas works with the tools you already own, correlates cloud activity with endpoint, network, identity, and email signals, and helps uncover permission issues, exposed services, leaked secrets, and overlooked attack paths. The result is a more connected view of risk and clearer action when suspicious activity appears.
