Percipion: the definitive sovereign engine for secure, sensitive text
Percipion is Aeteos’s symbolic cognitive platform. It turns messages, reports and seized language into inferences a human can inspect, on your infrastructure, without sending the corpus to a third-party model.
It does not predict the next word. It represents meaning, then reasons over that representation.
Built for law enforcement, defence, forensics and operators who cannot put classified or intimate text in front of a statistical system they do not control.
From raw text to a reasoned assessment
The analyst accepts, rejects or acts. Percipion does not close the case.
Ingest
Internal communications, Email archives, open sources, messaging, seized devices, or case files. On your premises.
Represent
Percipion maps language onto knowledge schemas, structured symbolic memory of concepts, relations, emotions and threat patterns.
Infer
It reads nuance: algospeak, emoji, grammar, valence, psychological drift, and how those signals evolve.
Explain & Act
You get a traceable assessment: what was found, why it matters, and what to watch next. No fabricated sources. No hidden model weights.
The same engine, two depths
Capacity follows the hardware you give it. There is no per-seat fee and no per-document fee.
The Sentinel
A light filter for live language, mail, messaging, forums, or a check on prompts sent to other systems. Selected schemas, including a law-enforcement-only set for serious crime. Use it alone, or integrated it as a microservice.
The Platform
The full engine licensed for one server or across the organization with all 29 software services and all 26 knowledge schemas. Analysis, inference, weak-signal detection, reasoning and explainable reporting.
Where teams use it
Cognitive warfare
Percipion detects weak semantic signals, psychological manipulation tactics, disinformation narratives and conspiracy theories in real time on social media and messaging platforms. It assesses whether content is harmful, triggers early warnings and supports swift reasoned counter-responses, a vital pillar of cognitive resilience and democratic defense in Europe.
Proactive threat detection
Leveraging advanced weak-signal detection, psychological profiling and contextual knowledge schemas, Percipion anticipates emerging threats, grooming, scams, bullying, radicalization, hate speech, terrorism planning and hybrid attacks, before they materialize. It tracks subtle shifts in semantics, emotion and intent across public and internal sources, delivering early warnings and powering total resilience strategies.
Insider threats
Percipion identifies grooming, coercion, psychological manipulation, and gradual disloyalty through deep analysis of internal communications. It detects rising negativity, emotional drift, and suspicious behavioral patterns, allowing security teams to intervene early and prevent data leaks, sabotage, or espionage from within.
Industrial espionage
Percipion monitors internal-supplier communications for signs of data exfiltration, IP theft, and foreign espionage. It uncovers subtle linguistic indicators and psychological coercion patterns, while its advanced document comparison capabilities help protect Europe’s strategic technologies and industrial sovereignty.
Forensic analysis
In post-incident or judicial contexts, Percipion rapidly processes content of seized devices and communications to reveal evidence of corruption, bribery, fraud, ransomware negotiations, or crime. Its explainable symbolic analysis and evidence report delivers court-admissible, traceable inferences in hours instead of weeks.
Supply chain risk monitoring
Percipion monitors supplier and partner communications for early signs of compromise, coercion, bribery, or sabotage intent. It detects psychological pressure, anomalous phrasing, and weak signals of supply-chain attacks, protecting Europe’s critical infrastructure from hidden vulnerabilities.
Built to stay on your side of the wire
The libraries in the engine are Aeteos’s. Source generation and error-checking are part of how the software is produced. That is a quality claim you can walk a technical evaluator through.

What “faster” means on seized text
A digital forensic analyst is working against a clock. One chat extract. 373 pages of plain text. Manual reading of that volume, done properly, is days of work. Custody does not wait days.
On that corpus Percipion produced a first pass in about a minute: passages ranked and tied back to schemas, for the analyst to inspect.
It does not replace the expert. It does not produce a finished judicial file. It removes the hours spent finding where to look.
In use, and written down
Deployments we can describe are on Success.
A comparison of labour, machine-learning stacks, LLMs and Percipion is in the profitability study (15 May 2026).
