Key Takeaways
- AI security assessments test your model, data pipelines, and access controls for vulnerabilities attackers exploit
- Most organisations deploying AI have never had one — and it shows in breach statistics
- A proper assessment costs far less than the reputational and financial damage of an AI-related incident
- The best time to do one is before you go live; the second-best time is right now
What Is an AI Security Assessment (and Why Most Organisations Get It Wrong)
An AI security assessment is a comprehensive evaluation of your AI systems — from the model itself through to the data pipelines feeding it, the infrastructure hosting it, and the people accessing it. Think of it as a security health check, but specifically designed for the unique risks that come with machine learning.
Here’s the thing though: most organisations think an AI security assessment is the same as a regular penetration test. It’s not. A pen test checks if someone can break into your servers. An AI security assessment checks if someone can trick your model, poison your training data, extract your intellectual property from the model itself, or hijack the system through prompt injection. These are completely different threats.
I’ve seen organisations spend hundreds of thousands on infrastructure security only to deploy a model that can be manipulated with a carefully crafted input. That’s the gap an AI security assessment fills.
Why AI Security Assessment Matters Now (More Than Ever)
You’ve probably noticed: AI adoption is accelerating. Every organisation is putting LLMs and AI systems into production. But security? Security hasn’t kept pace. The gap between how fast you’re deploying AI and how well you’re securing it is the problem we need to talk about.
Your AI systems are making decisions about customer data, financial transactions, and sometimes access control. If those systems can be manipulated or tricked, the person doing the manipulating can bypass the security controls you’ve built around everything else.
I worked with a client last year who had deployed a customer-facing AI agent that was pulling sensitive customer data when asked the right questions. Not because the agent was misconfigured — it was doing exactly what it was trained to do. But it had never been tested for data extraction attacks. An AI security assessment caught it before a customer or attacker did.
What Gets Tested in an AI Security Assessment
A proper AI security assessment covers several areas. Your organisation might not have all of them, but this is the full picture:
Model Vulnerabilities
Your AI model itself has attack surfaces. We test for prompt injection (feeding the model malicious instructions hidden in user input), jailbreaking (getting it to bypass safety guardrails), and adversarial inputs (inputs designed to cause incorrect outputs). We also assess whether the model has been properly fine-tuned or if it’s leaking training data.
Data Pipelines and Training Data
This is where a lot of hidden risk lives. We check how data flows into your model — is it validated? Is it sanitised? Can an attacker poison it? We also assess training data for contamination, bias that could be exploited, and whether sensitive data is present in the training set.
Access Controls and Authentication
Who can retrain your model? Who can access your model weights? Who can access the inference API? We map out the access control architecture and test whether it holds up. Overly permissive access is one of the most common findings.
Integration Points
If your AI system is integrated with other systems (databases, customer management systems, knowledge bases), we test those integration points. A model that’s secure in isolation can become a vulnerability vector when integrated poorly.
Infrastructure and Deployment
Where is the model hosted? How is it scaled? What happens if it gets deployed in an environment without proper isolation? We assess the operational security of your AI stack.
How Kapalins Does AI Security Assessment Differently
Most security firms do AI security assessment as an afterthought — they slap it onto a regular penetration test and call it done. We built our assessment methodology specifically for AI systems.
We test the actual risk scenarios. Not just theoretical vulnerabilities, but the attacks that would actually impact your business. If you’re using AI for customer support, we test whether the system can be tricked into bypassing policies or revealing confidential information.
We understand the broader context. An AI security assessment isn’t just about the model. It’s about how the model fits into your organisation — the people, the processes, the data.
We work in your environment. We test your actual infrastructure, your actual data pipelines, your actual integrations. Not in a sandbox, not against a generic model.
Who Needs an AI Security Assessment
If you’re using AI in any way that touches customer data, intellectual property, decision-making, or access control, you need one. But there are some organisations where it’s more urgent:
- Financial services and insurance: AI for fraud detection, underwriting, or claims processing needs an assessment.
- Healthcare: AI involved in diagnosis, treatment recommendations, or patient data access.
- Government and critical infrastructure: AI for regulatory decision-making or critical systems.
- B2B SaaS: AI systems exposed to customer input (chatbots, content filters, recommendation engines).
- Any organisation handling sensitive data: AI with access to customer data, financial data, or IP.
When Should You Do an AI Security Assessment
The best answer is: before you go live. The second-best answer is: right now if you’re already in production.
During development (ideal): Run an assessment in staging before production deployment.
At deployment: Do it as part of your go-live checklist.
After deployment: If you’re already in production without an assessment, prioritise this.
Ongoing: Plan to reassess periodically. Your threat landscape changes, your data changes, your team changes.
Common Findings We See in AI Security Assessments
- Overly permissive API access: Teams give broader access than necessary just to make integrations simpler.
- Insufficient input validation: Models are exposed to raw user input without any sanitisation or validation.
- No monitoring of model behaviour: Teams don’t have visibility into what the model is actually doing in production.
- Training data contamination: Sensitive data or malicious data in the training set affecting model behaviour.
- Poor access control to model weights: Anyone with system access can download and reverse-engineer the model.
The Investment vs. The Cost of Not Doing It
An AI security assessment costs money. Depending on the complexity of your systems, it could be anywhere from £5,000 to £50,000+ for a comprehensive assessment. But the cost of not doing one? Breaches caused by AI system vulnerabilities cost organisations 10x, 50x, or even more. Not just in direct financial loss, but in regulatory fines, brand damage, and customer churn.
AI Red Teaming Services — Going Deeper
If your assessment reveals significant vulnerabilities, the next step is often AI red teaming services. While an assessment is a structured security evaluation, red teaming is a more aggressive, ongoing adversarial simulation.
