AI Security Challenges While Maximising Business Value

01 September 2025

Artificial intelligence (AI) is transforming businesses, but security concerns have not gone away holding back its adoption. This guide reviews key AI risks such as data leaks, inaccuracies, cyber threats, biases and regulatory challenges and offers practical ways to mitigate them. See how managed cyber security Services and Financial services IT Support from Renaissance Computer services Ltd secure AI adoption so you can focus on productivity & growth.

Overview: Key Security Risks at a Glance

• Data Security: Sensitive data or intellectual property risked being exposed.
• Hallucinations: Artificial intelligence generating false or misleading outputs.
• Threat Actors: Cybercriminals exploit AI  enabled vulnerabilities.
• Biases: AI outputs that reflect unfair or discriminatory data patterns.
• Legal/Regulatory Issues: Laws like GDPR risking fines.

Understanding AI Security Risks

AI’s concerns fall into five main categories, each requiring specific strategies to address.

Data Security Challenges: Data powers AI but is also a target for breaches. LLMs learn from large datasets, and without proper controls, sensitive information like client financial records could be lost. For instance, a colleague using an open AI tool may share proprietary data with competitors or the public.

AI Hallucinations and Inaccuracies: AI hallucinations occur when models produce wrong or fabricated outputs. In high stakes environments like financial services, an inaccurate AI report could cost decisions. These errors are often caused by bad training data or unclear prompts therefore accuracy is paramount for businesses.

Cyber Threats and AI: Hackers are using AI to perform deepfake impersonations or automated phishing attacks. Without robust managed cyber security services, businesses run a greater risk of data theft or system breaches. 

Bias in AI Outputs: AI may acquire biased training data. Biased algorithms in financial services, for example might bias credit approvals in a way that hurts clients and reputations. Bias requires diverse datasets and ongoing vigilance.

Legal and Regulatory Hurdles: AI's Regulatory landscape is evolving, with laws like GDPR imposing strict data handling rules. Non-compliance can result in heavy fines - GDPR penalties hitting €1.2 billion in 2023 alone, Statista estimates. Businesses must steer through these rules without getting creamed, legally or reputationally.

Practical Steps to Mitigate AI Security Risks

Targeted strategies can make business use of AI while risks are minimised. Below are steps tailored for industries in finance that require Financial Services IT Support around the clock. 

1. Securing Your Data

A robust data governance framework will prevent data leaks:

• Classify and Encrypt: Label sensitive data (for example, client financial records) and encrypt it to avoid unlawful access.
• Access Controls: Use tools such as Microsoft Entra ID to enforce role-based access so employees can only access required data.
• Compliance: Ensure compliance with GDPR & industry standard to avoid fines and keep trust.
• Secure Storage: Implement cloud solutions with end-to-end encryption which is a part of a managed cyber security service offered by Renaissance Computer services Ltd.

Regular audits & employee training further reduce risks ensuring data stays within your organisation.

2. Reducing AI Hallucinations

To improve AI accuracy:

• Clean Data: Error-minimising models should be trained on high quality, current datasets.
• Effective Prompting: Use chain-of-thought prompts to have AI explain its reasoning to spot inaccuracies.
• Human Oversight: Have a human review of AI outputs, especially financial reporting.
• Prompt Refinement: Add instructions like "only give verified information" to limit fabricated responses.

Hence a financial firm using AI for market analysis should check outputs against trusted sources to avoid costly errors.

3. Countering AI-Driven Cyber Threats

Cybercriminals will always exploit AI but businesses can fight back with managed cyber security services:

• Zero-Trust Security: Verify each user/device before granting access using tools like multi-factor authentication.
• Regular Testing: Perform penetration tests & vulnerability scans to discover weaknesses.
• AI for Defence: Detect patterns of malicious activity (for example strange login attempts) using AI powered security tools.

24/7 Monitoring: Partner with providers such as Renaissance Computer Services Ltd for 24/7 threat detection.

4. Addressing AI Bias

To minimise bias:

• Diverse Datasets: Train AI with representative data.
• Regular Audits: Check AI models for bias - especially in financial services - fairness is important.
• Human Input: Augment AI insights with human judgment for ethical decisions.
• User Training: Education for staff to spot/report biased outputs.

For instance, a loan approval AI should be audited to ensure it doesn’t discriminate based on gender or ethnicity.

5. Navigating Legal and Regulatory Risks

To stay compliant:

• AI Governance: Create internal AI use policies regarding data privacy & ethical concerns.
• Trusted Tools: Choose AI platforms from reliable providers that meet GDPR and industry standards.
• Supplier Vetting: Mitigate third party AI vendor supply chain risk by ensuring they follow responsible practices.
• Transparency: Tools that explain their decision-making will increase compliance and trust.

With regular legal reviews your AI practices remain inline with changing laws.

Choosing the Right AI Tools

AI tools are not created equal. When selecting platforms, consider:

• Security: Seek robust encryption & access controls.
• Fairness: Use bias detection tools.
• Transparency: Prioritise platforms which explain their outputs.
• Compliance: Check that tools meet GDPR and industry standard.
• Integration: Choose solutions that work with existing systems - like Microsoft Copilot for financial firms.

Renaissance Computer Services Ltd recommends Microsoft Copilot, which integrates with Azure and Fabric for enhanced security and compliance, making it ideal for Financial Services IT Support.
