Security Intelligence by Design
Ravencord develops active security intelligence systems for institutions where a single breach carries regulatory, operational, or national consequence. Our platforms are not bolted on. They are architected into the operational fabric of the organization.
Behavioral profiles, threat detection logs, and data movement patterns are among the most sensitive assets an organization generates. Our security systems run entirely on your infrastructure: air-gapped capable, fully sovereign, zero external exposure.
Our Approach
We architect software around tangible workflows rather than abstract theory, empowering institutions to operate with precision and confidence across all sectors. Every system is engineered to be inherently auditable and maintainable, ensuring seamless alignment with rigorous operational requirements from the outset.
Behavioral profiles, data movement logs, and threat detection data are among the most sensitive assets an organization generates. Everything we build runs on your hardware, under your control.

Active Threat Systems
These are not off-the-shelf tools. Each system is engineered for environments where standard security posture is structurally insufficient.
UEBA: User & Entity Behavior Analytics
We build behavioral profiling systems that establish institutional baselines and detect anomalies in real time. This includes unusual access patterns, off-hours activity, bulk data movement, and privilege escalation, catching them before they escalate into incidents.
DLP: Data Loss Prevention
Our DLP systems enforce data boundaries at the file, endpoint, and network layer. Sensitive data is classified, monitored, and protected across every egress channel with policy engines that block, alert, or escalate based on real-time risk scoring.
Deception Technology
We deploy synthetic environments across infrastructure, including fake credentials, decoy systems, and honeypot assets. These are invisible to legitimate users but irresistible to attackers. Contact with any deception layer triggers immediate, high-confidence alerts with zero false positives.
OT / SCADA Security
Industrial control systems and SCADA infrastructure were engineered for reliability, not security. We harden operational technology environments like energy grids, water systems, and manufacturing facilities where a successful cyberattack produces physical consequences.
Digital Twin Security
We build virtual replicas of critical infrastructure to simulate attack scenarios, test defensive architectures, and identify vulnerabilities before they exist in production. Threat modeling against a digital twin eliminates the risk of security testing on live systems.
Supply Chain Integrity Monitoring
Modern breaches don't enter through the front door. We build continuous monitoring systems that track software dependencies, third-party access patterns, and component integrity, alerting on anomalies before they propagate inward.
Threat Intelligence Platform
Raw global threat data has limited operational value unless filtered through the lens of your sector, geography, and infrastructure profile. We build contextualized intelligence platforms that translate external threat signals into institution-specific defensive priorities, so you know what's coming for organizations like yours before it arrives.
Validated in Security-Critical Environments
Our systems operate under high-availability requirements, strict security constraints, and infrastructure-grade standards. We test functionality, resilience, auditability, and long-term operational integrity.
Case Example: USM (Unified Security Monitor)
USM is a comprehensive on-premise security intelligence platform combining UEBA, DLP, and intelligent correlation into a unified threat detection system. Deployed for a multinational energy infrastructure company, USM monitors user behavior patterns across 2,500+ endpoints, detects anomalies using machine learning (Isolation Forest), enforces data loss prevention policies with real-time file scanning for sensitive data (PII, financial records, credentials), and correlates cross-system signals to identify complex attack patterns such as insider threats, data exfiltration, and lateral movement. Features include automated risk scoring with configurable thresholds (LOG/WARN/BLOCK/LOCKDOWN), real-time dashboard with live event streaming, and full audit trail logging for regulatory compliance.
Case Example: Nordic Grid Monitor, OT/SCADA Threat & Operations Intelligence
Nordic Grid Monitor is an on-premise operational intelligence platform deployed for a Nordic energy grid operator managing 400+ OT devices across high-voltage substations and distributed SCADA nodes. The system provides real-time anomaly detection across Modbus, DNP3, and IEC 61850 protocols using a time-series database (TimescaleDB on PostgreSQL) combined with an Isolation Forest ML model trained on 18 months of baseline operational data. Any deviation from established process norms — unexpected register writes, unauthorized PLC polling, irregular GOOSE message timing, triggers a prioritized alert with full packet-level forensic context.
The platform enforces strict network segmentation monitoring between IT and OT zones, detecting lateral movement attempts with sub-second precision. A passive asset inventory module continuously maps the live device topology without injecting traffic into the control network. All data is retained on-premise with cryptographic audit trails aligned to NIS2 and IEC 62443 requirements. Deployed air-gap capable with optional out-of-band alerting via encrypted SMS gateway.
Stack: TimescaleDB · PostgreSQL · Python (scikit-learn, Isolation Forest) · Zeek IDS · Grafana (air-gapped) · Modbus/DNP3/IEC 61850 parsers · Encrypted SMS gateway
Case Example: Finlex Pro (EU Financial Regulation Intelligence)
Finlex Pro is a comprehensive EU financial regulation search platform providing instant access to 2,400+ indexed documents across MiCA, DORA, AML Regulation (AMLR), AMLD6, AMLA, Transfer of Funds Regulation (TFR), PSD2, EMD2, MiFID2, SFDR, and ESMA/EBA Guidelines. Features include intelligent keyword matching with synonym expansion, article-level citation accuracy, AI-powered regulatory analysis, and CJEU case law integration for compliance teams, legal professionals, and financial institutions.
Inside the Build: Nordic Grid Monitor
A closer look at the architecture and engineering decisions behind a production OT/SCADA security platform deployed for a critical energy infrastructure operator.
Time-Series Data Architecture
All OT telemetry is ingested into TimescaleDB, a PostgreSQL extension purpose-built for high-frequency time-series data. Continuous aggregates compress 400+ device streams into queryable hypertables without degrading write throughput. Retention policies enforce 24-month rolling storage with cryptographic checksums per chunk.
ML Anomaly Detection Pipeline
An Isolation Forest model trained on 18 months of baseline SCADA telemetry scores every incoming process value against expected operational ranges. Contamination threshold is tuned per device class: stricter for protection relays, looser for environmental sensors. Anomaly scores feed a priority queue; anything above 0.85 triggers immediate analyst escalation.
Protocol-Level Passive Monitoring
Zeek IDS parses raw OT protocol traffic (Modbus TCP, DNP3, and IEC 61850 GOOSE/MMS) without injecting a single packet into the control network. Custom Zeek scripts extract register addresses, function codes, and GOOSE dataset identifiers, flagging unauthorized reads, unexpected write commands, and timing deviations that signature-based tools never catch.
IT/OT Segmentation Enforcement
A dedicated segmentation monitor correlates firewall logs, switch port data, and DNS queries to detect lateral movement between IT and OT zones. Any host that appears in both zones within a configurable time window generates a cross-zone alert. Asset discovery runs passively from mirrored traffic with zero active scanning and zero impact on control processes.
NIS2 & IEC 62443 Audit Trail
Every event, acknowledgment, and configuration change is written to an append-only audit log with per-record HMAC signatures. Log integrity can be verified offline with no dependency on the running system. Structured exports map directly to NIS2 Article 21 incident reporting fields and IEC 62443-2-1 security management records.
Air-Gap & Out-of-Band Alerting
The platform is deployable in fully air-gapped environments with no external network dependency. High-priority alerts are delivered via an encrypted SMS gateway connected through a dedicated hardware serial channel, fully isolated from the monitored network. Grafana dashboards run entirely on-premise with no telemetry to external services.
