Introducing Excalibur
A private AI system that does the work of an entire security department. Discovers threats, validates exposures, predicts where the next attack will land, and gets smarter every cycle.
Your premises. AI that evolves. Data that stays.

The Problem
“Which crown-jewel asset is being targeted next, and how?”
AI has weaponized the attack timeline. State-sponsored actors are automating 80 to 90% of campaigns.¹ The window from disclosure to exploitation has collapsed from days to minutes. Human-led defense cannot keep up.
The average enterprise runs dozens of siloed security tools. This fragmentation does not create safety. It creates alert fatigue. When everything is a priority, nothing is. Analysts drown in noise, missing the signals that matter.
Enterprises will not send crown-jewel data to cloud AI vendors. General-purpose LLMs have zero training on your OT systems or infrastructure. The market is moving to sovereign AI that stays inside your walls.
The game changed. Your defense didn’t. The shift is from “How do I use AI?” to “How do I build an AI that belongs only to me?”
The Solution
Excalibur replaces your fragmented security stack with one closed-loop system. It automates 80% of the manual work your team currently does, ingests your existing tools, predicts where the next attack will land, and gets smarter every cycle. Privately. On your hardware.
Automate
9 native security modules pre-loaded. These are not tools. They are entire capabilities that run the repetitive work so your team can focus on decisions.
Connect
Plug into your existing stack. Wiz, CrowdStrike, MS Defender, Qualys. We turn your scattered tools into one unified Source of Truth.
Predict
Excalibur fuses data from all 9 modules and your external connectors to answer one question: Where is the next attack coming from, and how do we stop it?
Evolve
Every alert, every scan, every daily operation is a lesson. Excalibur retrains its own models privately on your hardware. The longer you own it, the harder you are to hack.
From a customer

I was initially skeptical about AI’s impact on the cybersecurity industry, until I started working with Excalibur.
Excalibur’s modules and technology have significantly improved my ability to manage multiple security frameworks and architectures. The Posture model delivers actionable insights that enhance the effectiveness of Tier 1 analysts while providing an excellent learning path, reducing the time I need to spend on foundational training. It also does an outstanding job of modeling potential threats and identifying security concerns.
The recently introduced Govern model is ahead of the curve when it comes to reducing the time required for compliance management and audit preparation. The ability to answer framework-specific questions simply by uploading policy documents is a tremendous time saver. Our previous platform, Apptega, which remains a solid solution in terms of cost and capabilities, could not extract answers directly from documentation, making this feature a true game changer.
I firmly believe AI should be used to make security professionals more effective and efficient, freeing them to focus on meaningful security work rather than replacing jobs. Excalibur fully embraces that philosophy and continues to deliver rapid innovation and improvement.
I’m excited to see where this product goes next.
