NEW! Semantic AI
Contextual AI email security engine that reads between the lines.
Libraesva have added a powerful new layer of protection called Semantic AI. This has been built to analyse the intent and context behind every email – Not just the content. It detects hidden threats, subtle anomalies and malicious behaviour even in legitimate-looking threads, stopping attacks that traditional filters often miss.
Running alongside their Adaptive Trust Engine, Semantic AI is lightweight, fast and secure, with no reliance on cloud services or third-party APIs. Built entirely in-house, it delivers clear, consistent protection without adding attack surface or complexities, helping you and your customers stay ahead of today’s most advanced email threats.

The benefits of Semantic AI
Clarity
Semantic AI doesn’t create, it classifies. It uses the same neural network and tensor-based technology as generative AI to deliver precise threat classification, with no hallucinations and no synthetic outputs.
Contextual irregularities are identified
Why would your customers’ CFO reference a payment link to a client they’ve never dealt with? Instead of looking for keywords or behavioural signatures, Semantic AI picks up on the inconsistencies in logic or context that rule-based engines can miss.
Smarter and faster operation
This isn’t a generic trillion-parameter language model trained on internet noise. Libraesva’s engineers have created an agile 100M-parameter model trained on thousands of curated real-world threat examples. With latency of less than a second, Semantic AI runs on standard CPU hardware, which means no delays, no GPUs and no need to offload to the cloud.
Day zero detection
During internal testing, Semantic AI detected fake ADSL subscription scams on Day 0, before any signature updates or pattern propagation. It proactively interprets anomalies in communication, catching threats early and decisively.
Parallel protection
The Libraesva Semantic AI engine adds a deeper layer of scrutiny to your customers’ existing protection without adding complexity.
Discriminative intelligence
Unlike generative models, which introduce random variability into their results, Semantic AI is discriminative. The same email will always yield the same output for the consistent, reliable classification that’s essential for security reliability.
Weekly retraining with high-frequency updates
Libraesva’s agile approach ensures rapid responsiveness to emerging threats without burdening your customers’ system with full retraining cycles.
Semantic AI’s language model is initially trained on the semantics of 100 languages for broad foundational semantic understanding. The base model is then fine-tuned for email classification using curated threat examples – this takes just a few hours, and updated models can be deployed within minutes.
