Different Layers of the AI Stack: Testing vs Governance
The AI stack has distinct layers, and confusing them leads to dangerous governance gaps. Robust Intelligence operates at the model validation layer - answering questions like "Does this model produce biased outputs?", "Can adversarial inputs cause this model to behave unsafely?", and "Does this model meet our quality thresholds for deployment?" These are critical questions, and Robust Intelligence built strong technology to answer them.
Areebi operates at the operational governance layer - answering questions like "Who used this model today, for what purpose, and with what data?", "Was sensitive data exposed to any AI model?", "Can we prove compliance to an auditor?", and "What unsanctioned AI tools are employees using?" These questions arise not once at deployment, but thousands of times per day in every AI interaction across the organisation.
The distinction is analogous to penetration testing versus a firewall. You need both, but they serve different purposes at different times. Robust Intelligence pen-tests your AI models before deployment. Areebi is the operational control plane that governs every interaction after deployment. An organisation that has only model validation but no operational governance is like a company that pen-tests its applications but has no WAF, no DLP, and no access controls in production.
The Cisco Acquisition: From Startup to Platform Module
Cisco acquired Robust Intelligence for approximately $400M in 2024, rebranding it as Cisco AI Defense. This followed the broader 2024–2025 acquisition wave that absorbed seven AI security startups into infrastructure vendors. The pattern is consistent: the standalone product becomes a module within the acquirer's platform, and the engineering team's roadmap is redirected to serve the parent company's strategic priorities.
For Cisco, AI Defense serves a specific role: it strengthens Cisco's security portfolio narrative by adding "AI security" capabilities alongside the existing network security, endpoint security, and cloud security offerings. But Cisco's customers are being directed to consume AI Defense as part of the Cisco security stack - not as an independent product. This means new customers face Cisco's enterprise sales process, Cisco's bundling requirements, and Cisco's infrastructure assumptions.
More fundamentally, Cisco's AI Defense inherits Robust Intelligence's original scope: model validation and testing. Cisco has not added the operational governance capabilities - DLP, policy engine, audit trails, shadow AI detection, compliance automation - that enterprises need for day-to-day AI governance. For organisations seeking a complete AI governance solution rather than a model testing module within a network security stack, Areebi provides the operational layer that Cisco AI Defense does not address.
Complementary Tools or Replacement? The Honest Answer
In the spirit of accuracy: Robust Intelligence (Cisco AI Defense) and Areebi are largely complementary rather than directly competitive. They address different stages of the AI lifecycle. Robust Intelligence validates models before deployment; Areebi governs model usage after deployment. An organisation could theoretically use both.
However, the practical reality for most enterprises is that operational governance is the more urgent need. Model validation matters, but the immediate risks - employees sharing sensitive data with AI models, unsanctioned AI tools proliferating, inability to demonstrate compliance to auditors - are operational governance problems, not model validation problems. When a board asks "How are we governing AI risk?", they are asking about data protection, policy enforcement, and audit trails - not about whether a model passed adversarial testing.
For enterprises that must prioritise, Areebi addresses the more immediate and pervasive governance need. If your organisation also develops or fine-tunes custom AI models, pre-deployment validation tools like Cisco AI Defense serve a distinct purpose. But for the majority of enterprises that consume AI through APIs and SaaS products, operational governance is the critical gap - and that is precisely what Areebi was built to fill. Take the AI governance assessment to understand which layer of governance your organisation most urgently needs.
The Operational Governance Stack Robust Intelligence Never Built
Robust Intelligence's capabilities - model validation, adversarial testing, bias detection, model performance monitoring - are valuable but cover a narrow slice of what enterprise AI governance requires. Here are the operational capabilities that Areebi provides and that Robust Intelligence (Cisco AI Defense) does not offer.
Real-time DLP scans every prompt and response for sensitive data - PII, PHI, PCI, secrets, proprietary information - and takes action (block, mask, approve, escalate) before data reaches the model. Policy engine enforces identity-aware rules about who can use which models for which purposes, with a visual builder that compliance teams can operate. Decision provenance records exactly why each AI interaction was permitted, blocked, or modified - providing the audit trail that HIPAA, EU AI Act, and SOC 2 auditors require. Shadow AI discovery identifies every unsanctioned AI tool in use across the organisation, not just the models you have chosen to validate.
Additionally, Areebi provides incident replay (reconstruct what AI saw during a failure), model registry (catalogue all models with risk scores), cost allocation (track AI spend by user, team, and model), workspace isolation (enforce data boundaries between teams), and compliance automation (generate evidence packages pre-mapped to regulatory frameworks). These are not incremental features - they are the core infrastructure of enterprise AI governance. Request a demo to see the full operational governance stack in action.
Frequently Asked Questions
Is Robust Intelligence still available as a standalone product?
Robust Intelligence was acquired by Cisco for approximately $400M in 2024 and rebranded as Cisco AI Defense. The standalone product is being absorbed into Cisco's security platform. New customers are directed through Cisco's enterprise sales process and may need to adopt broader Cisco infrastructure. Existing customers face migration to the Cisco-integrated offering.
Our security team uses Cisco AI Defense for model validation. Do we still need Areebi?
Yes - they address different problems. Cisco AI Defense validates whether a model is safe to deploy. Areebi governs how that model is used every day after deployment: who accesses it, what data flows through it, whether interactions comply with policy, and whether you can prove governance to auditors. Model validation without operational governance is like penetration testing without a firewall.
Does Areebi do any model validation or red teaming?
Areebi's model registry includes basic risk scoring for catalogued models, and Areebi's input enforcement layer catches adversarial prompts (prompt injection, jailbreak attempts) at runtime. However, Areebi does not provide the deep pre-deployment model validation and systematic adversarial testing that Robust Intelligence specialised in. If you need both, Areebi for operational governance and a model validation tool for pre-deployment testing can coexist.
Which should we buy first - model validation or operational governance?
For most enterprises, operational governance is the more urgent need. The immediate risks - sensitive data leaking through AI prompts, employees using unsanctioned AI tools, inability to demonstrate compliance - are operational problems. Model validation is important for organisations developing or fine-tuning custom models, but most enterprises consume AI through APIs and need governance of that consumption first.
How does pricing compare between Cisco AI Defense and Areebi?
Cisco AI Defense is priced as part of the Cisco security stack, typically requiring existing Cisco infrastructure and enterprise-level commitments - estimated at $80,000–$200,000+ annually depending on scope and bundling. Areebi is $48,000–$84,000/year for 200 users with no prerequisite infrastructure, no bundling requirements, and transparent per-seat pricing. Areebi also delivers operational governance capabilities that Cisco AI Defense does not provide.
