Cloud security consulting from DeepSeas helps organizations understand, reduce, and manage risk across cloud environments. Consultants assess identity, permissions, configurations, exposed services, detection coverage, and connections between cloud and on-premises systems. With approximately 30 years of cyber defense experience, DeepSeas delivers practical guidance that supports stronger protection, clearer priorities, and measurable cybersecurity outcomes.
DeepSeas combines cloud assessment, advisory, testing, compliance, and managed defense to address security risks across your environment.
DeepSeas tests IaaS, PaaS, and SaaS environments through manual validation and adversary simulation. Consultants examine identity, permissions, configurations, exposed services, APIs, secrets, logging, and cloud-to-on-premises attack paths.
Cloud-focused cybersecurity risk assessments examine assets, controls, vulnerabilities, business impact, and likelihood. The resulting plan prioritizes practical risk treatment and supports compliance, governance, and executive decision-making.
DeepSeas builds cloud security programs around business goals and actual risk, covering governance, policies, standards, metrics, decision rights, operating processes, and a roadmap for continuous improvement.
Senior advisors help leaders make defensible cloud security decisions, including technology strategy, program priorities, acquisition preparation, board reporting, insurer reviews, and capability planning.
A DeepSeas vCISO provides security leadership for strategy, governance, risk management, controls oversight, executive reporting, compliance guidance, and transformation planning without requiring a full-time executive hire.
DeepSeas develops cloud-relevant governance and compliance programs with control mapping, evidence organization, gap assessments, policy development, and continuous controls monitoring for audit readiness.
Cloud environments change quickly, and security weaknesses often arise from identity, permission, configuration, secrets, and trust relationships rather than a single missing patch. DeepSeas consultants assess the paths an attacker could use to reach data, workloads, or administrative control, then connect findings to remediation, governance, detection, and business priorities. The result is practical guidance your team can understand, prioritize, and apply.
