Bordair vs Lakera Guard: A Better Alternative for Prompt Injection Detection

If you are evaluating prompt injection detection tools, you have probably come across Lakera Guard. It is one of the more established products in this space. But it is not the only option, and depending on your needs, it might not be the best one.

Here is an honest comparison between Bordair and Lakera Guard to help you decide.

Detection approach

Lakera Guard uses a proprietary ML model trained on their internal dataset. Detection is text-only for the core product, with limited multimodal support.

Bordair uses a three-stage pipeline: pattern matching (sub-1ms), fast-accept gate, and a fine-tuned DeBERTa v3 classifier. Total latency is under 50ms. We support text, image, document, and audio inputs natively.

Multimodal support

This is where the gap is widest. Modern LLM applications accept images, PDFs, audio, and more. Attackers are already exploiting these channels with techniques like OCR injection, EXIF metadata poisoning, and steganographic embedding.

Bordair scans all four modalities. We extract text from images via OCR, parse document metadata and hidden layers, and transcribe audio before classification. Lakera's core product focuses primarily on text.

Latency

Bordair's pattern matching layer catches known attacks in under 1ms. The full ML pipeline completes in under 50ms. This matters when you are adding security to a real-time chat interface or an API that needs to respond quickly.

Pricing transparency

Bordair offers a generous free tier (1,000 scans per month) and straightforward paid plans. No sales calls required to get started. You can sign up and have detection running in under five minutes.

Output scanning

Bordair includes regex-based output scanning on paid plans. You can define custom rules with block, redact, warn, or log actions. This lets you catch sensitive data, PII, or unwanted patterns in LLM responses before they reach your users.

Open-source commitment

We have open-sourced our multimodal test suite (23,759 cross-modal payloads) so the community can evaluate detection tools independently. Transparency matters in security tooling.

When to choose Lakera

• You only need text-based detection and are already integrated
• You are locked into an enterprise contract that includes Lakera
• Your compliance requirements specifically name Lakera

When to choose Bordair

• You need multimodal detection (images, documents, audio)
• You want sub-50ms latency without sacrificing accuracy
• You want output scanning with custom rules
• You want transparent, self-serve pricing
• You value open-source transparency in security tooling
