A data-driven intelligence layer built for modern enterprises and resource-constrained security teams.
Market intelligence reveals structural gaps that cannot be solved by adding more tools.
The majority of small and medium businesses operate with zero to one dedicated security professional, creating critical coverage gaps across identity, cloud, and endpoint domains.
Tool sprawl has become structural. Each additional SaaS application introduces new identity surfaces, data flows, and vendor relationships that multiply attack vectors exponentially.
SOC teams receive thousands of daily alerts while investigating fewer than 50%. False positive fatigue has become a structural vulnerability, not a process failure.
Modern ransomware achieves lateral movement within minutes. Human-speed response cannot match adversary timelines, requiring pre-positioned intelligence and automated decision support.
A three-layer architecture that transforms fragmented security telemetry into defensible executive decisions.
Hover over items to see details • Data flows continuously from signals to decisions
Follow the decision lifecycle from raw signals to recorded institutional knowledge.
Telemetry from identity, endpoint, cloud, and vendor systems
Fragmented alerts across 70+ tools
Unified signal stream
Immutable decision records with full reasoning chains, governance mapping, and risk tradeoffs.
Key questions from security leaders, architects, and investors.
CISOs, security architects, and SOC leaders who need to make defensible decisions in complex, multi-vendor environments. Especially valuable for teams operating with limited staff but facing enterprise-scale security challenges.
SOC tools aggregate data and automate responses. LegionSDI provides decision intelligence — explaining why risk exists, how entities relate, and what tradeoffs matter. It sits above operational tools as an intelligence layer.
No. LegionSDI is read-only. It observes, reasons, and recommends. Humans retain full control over response decisions. This design ensures auditability and eliminates automation risk.
Initial intelligence begins within 72 hours of integration. Full ontology construction typically completes within 2-4 weeks depending on environment complexity. No professional services required.
The ontology model is inherently scale-agnostic. SMBs benefit from decision support that compensates for limited staff. Enterprises benefit from unified intelligence across fragmented tool estates.
Identity (Okta, Azure AD), Endpoint (CrowdStrike, Defender), Cloud (AWS, Azure, GCP), SaaS, Vendor Risk, and GRC platforms. Read-only API access. No inline network inspection.
Read-only API credentials with minimum required scopes. No write access. No data path interception. Audit logs for all platform access. SOC 2 Type II certified infrastructure.
Security spending is $185B+ annually yet breaches accelerate. The gap is not detection — it is decision-making. LegionSDI addresses a structural market failure with a category-creating approach.
LegionSDI is built for a world where security decisions must be made continuously, defensibly, and at scale — even when humans cannot be present.
