The steps of our tradecraft

Increase ROI on existing security technology investments

The DeepSeas Cyber Defense Platform integrates with leading enterprise security tools to allow our cyber defense team to harden your defenses, identify threats, and take remediation actions.


The DeepSeas Cyber Defense Platform Makes Your Existing Security Tools Better.


Our Open XDR strategy allows you to maximize the impact of your existing security tech.

The DeepSeas Cyber Defense Platform unlocks extended detection and response (XDR) use cases, utilizing security technologies you may already have. Rather than asking you to replace security tools you have previously made procurement and deployment investments in, we directly integrate with your existing security tools and help you configure them for maximum environment visibility and threat detection impact.

We understand that your security needs are unique, so we meet you where you are on the cyber maturity voyage and help you forge ahead. Our costumer portal can provide you with a turn-key cyber defense command center to help you track threat defense workflows and program metrics, as well as directly interact with our team. Alternatively, our platform API framework enables flexible integration with security service management tools you already use today.


Continuously Improving


Attackers are people. The techniques attackers use are dynamic and evolving, and so are we.

You can count on us to bring unique innovations that continue to increase the depth, scale, and value of your cyber defense program. Examples of our unique solution investments include our machine learning powered advanced threat hunt platform, technical cyber attack simulation that helps verify how effective in-place tools are working, and our low cost log management solution that can contribute to optimizing SIEM license costs.

You’ll benefit from our continuous innovation and people development roadmap. Our relationship together will be high touch, as we partner with you to assess, defend, and mature your cyber defense program.

Our Client Outcomes

When the cyberseas become dangerous, we take our customers to calm waters.

Guiding a Defense Contractor from Ransomware Resilience to Scaled Cyber Inoculation

When the notorious REvil ransomware group compromised Kaseya enterprise software and used it to spread destructive ransomware – we held the line. Before this attack was publicly disclosed, our Cyber Fusion Team detected and eradicated it within one of our customer networks. Based on the intelligence we gathered, we were then able to immediately inoculate all of our customers against the threat.

A Manufacturer Defeats Advanced Threat Actor Fileless Malware Attack

In the second half of 2022, advanced threat actors began exploiting vulnerabilities in a software product called Zoho ManageEngine. When a hacker used this exploit to move laterally into an environment that was defended by our team, we detected and removed the bad actor who was using “living off of the land” techniques (i.e. no malware).

Cyber Response Leadership Protects Customers During Log4Shell Critical Global Zero-Day Vulnerability

In late November of 2021, a new, high-impact, zero-day vulnerability was discovered in the Log4J code library that is embedded in countless internet-exposed web applications. Within hours of the vulnerability’s disclosure, our team pushed flash notifications to customers, deployed updated detection logic, and began monitoring Log4Shell exploitation attempts. As days followed, our cyber defense leaders provided remediation and impact assessment guidance that helped defend our clients’ environments and give them clearer minds.
