The Biggest Security Risks Facing Businesses Right Now

Artificial intelligence is quickly becoming a business priority. Organisations are investing in tools to improve productivity, automate processes and unlock new insights from their data. At the same time, many are continuing their modernisation journeys, moving applications to the cloud and embracing more flexible ways of working.

However, while the opportunities are significant, so are the risks.

Many businesses are racing ahead with AI adoption without the security foundations needed to support it. As organisations become more connected, more data-driven and increasingly reliant on digital platforms, the attack surface continues to expand.

Cyber security is no longer just an IT concern. It is a business-critical priority that can directly impact productivity, reputation, growth and innovation.

Here are the biggest security risks businesses are facing right now, and why addressing them is essential before scaling AI initiatives.

1. Identity attacks are becoming the primary entry point

The traditional network perimeter is disappearing.

Employees work across multiple devices, applications and locations. Business-critical systems are increasingly cloud-based. As a result, attackers are no longer trying to break through firewalls. They are targeting identities instead.

By stealing credentials, exploiting weak passwords or bypassing poorly configured authentication controls, cybercriminals can gain access to systems while appearing to be legitimate users. Identity-based attacks have become one of the most effective ways for attackers to move undetected through businesses.

The challenge becomes even greater when organisations adopt AI tools. Many AI platforms have access to emails, documents, files and business data. If an attacker compromises a user’s account, they may also gain access to the information powering those AI systems.

What organisations should focus on:

• Multi-factor authentication (MFA)
• Conditional access policies
• Identity monitoring and threat detection
• Regular access reviews
• Passwordless authentication and passkeys

The future of cyber security starts with protecting identities.

2. Shadow AI is creating new blind spots

AI adoption is happening faster than many businesses realise.

While leadership teams may be evaluating approved AI solutions, employees are often experimenting with their own tools. They may use public AI applications to summarise documents, analyse spreadsheets or generate content, often without understanding where that information is being stored or processed.

This phenomenon, known as Shadow AI, is rapidly becoming one of the biggest security and governance challenges organisations face.

The risks include:

• Sensitive data being shared with unauthorised platforms
• Intellectual property exposure
• Loss of visibility over how business information is used
• Compliance and regulatory concerns
• Inaccurate AI-generated outputs being used in decision-making

The problem is not AI itself. The problem is using AI without proper oversight.

Businesses need clear policies, user education and governance controls to ensure AI is adopted safely and responsibly.

3. Poor access controls leave data exposed

Many organisations still operate on a simple principle: once a user is inside, they can access almost everything.

As businesses grow, acquire new technologies and create more data, these permissions often become difficult to manage. Employees retain access to systems they no longer need. Shared accounts remain active. Former users are not always removed promptly.

The result is unnecessary risk.

Modern AI solutions rely on access to data to deliver value. However, if permissions are poorly managed, AI can inadvertently show sensitive information to users who should not see it.

Before organisations can trust AI, they need confidence in who can access what. That means applying least-privilege principles and granting access only where someone genuinely needs it.

Key questions to ask:

• Do employees only have access to the information they need?
• Are privileged accounts properly secured?
• How often are permissions reviewed?
• Can you quickly identify excessive or risky access?

The quality of your access controls directly impacts the security of your data.

4. Legacy systems continue to hold businesses back

Many organisations want to embrace AI but remain reliant on ageing infrastructure.

Legacy systems create significant challenges:

• Unsupported software
• Missing security updates
• Limited visibility
• Integration issues
• Higher operational costs

Beyond increasing cyber risk, these systems often prevent businesses from fully benefiting from modern technologies.

AI depends on secure, accessible and well-managed data. Legacy platforms frequently create data silos, making it difficult to connect information across the business and limiting the effectiveness of AI-powered insights.

Modernisation is not just about improving efficiency. It is about creating a secure platform for future innovation. Businesses that delay modernisation often find themselves spending more money maintaining outdated technology while increasing their security exposure.

5. Data exposure remains a growing concern

Data has become one of the most valuable assets organisations possess. It is also one of the most targeted.

Whether caused by cyber attacks, human error, misconfigured cloud environments or poor governance, data exposure can have severe consequences. Financial loss, operational disruption, regulatory penalties and reputational damage are just a few of the risks.

As AI adoption grows, the importance of data security becomes even greater.

AI tools depend on high-quality business data. If that data is inaccurate, poorly governed or exposed to unauthorised access, the results can be problematic.

Before asking whether your business is ready for AI, a more important question may be:

Is your data ready?

Organisations need visibility over:

• Where their data resides
• Who can access it
• How it is classified
• How it is protected
• How it is being used

Without this foundation, AI initiatives can introduce more risk than value.

Security is not a barrier to innovation

Too often, cyber security is viewed as something that slows progress. In reality, the opposite is true.

The organisations seeing the greatest success with AI and digital transformation are those that have invested in strong foundations first. They understand that security, governance and modern infrastructure are not obstacles to innovation, they are what make innovation possible.

By strengthening identity security, improving access controls, modernising legacy systems, managing Shadow AI and protecting data, businesses can adopt AI with greater confidence and unlock more value from their technology investments.

The organisations that thrive over the next decade will not necessarily be those that adopt AI the fastest. They will be the ones that build the strongest foundations to support it.

Thinking about scaling AI across your organisation? Start by assessing your security foundations. The right cyber strategy helps you innovate faster, reduce risk and get more value from your technology investments.
