The Future of Cyber Security: Trends to watch in 2025

sales@minstermicro.co.uk

As 2025 approaches, cyber security has become critical for businesses. With cyber attacks growing more sophisticated, organisations and employees must constantly adapt to an evolving threat landscape. The increasing connectivity of machinery and devices, or IOT (internet of things), poses new challenges for companies striving to maintain robust security.

Completing an annual cyber questionnaire for insurers or renewing your Cyber Essentials accreditation is not enough. Cyber security must be an integral, continuous focus for businesses - 24/7. Treating it as a mere tick-box exercise will leave you and your business dangerously exposed to cyber criminals and potential breaches. The cost of down-time is just one component - your reputation is equally important. On top of this, fines that the ICO (Information Commissioner's Office) can impose for data breaches means that you simply cannot ignore how significant cyber has become.

So, how can you protect your business, and what should you prepare for in the year ahead?

Here are some key trends in cyber to watch out for:

1. AI-Powered Cyber Security

Artificial Intelligence (AI) is transforming cyber security by enabling faster threat detection, automating responses, and predicting vulnerabilities in real time, significantly reducing reaction times. By 2025, the number of companies investing heavily in AI for cyber defence is expected to nearly double. However, cyber criminals are also using AI to develop more sophisticated attacks, intensifying the cyber security arms race. This evolving battleground requires constant vigilance—ignoring AI's role in cyber security will leave your business more vulnerable than ever.

2. Zero Trust Architecture

The 'zero trust' security model, which operates on the principle of 'never trust, always verify' is set to become the dominant protection strategy by 2025. As hybrid work environments spread employees, devices, and data across multiple locations, zero trust frameworks will help mitigate insider threats, reduce attack surfaces, and enforce granular access control across all endpoints. This approach is especially crucial for organisations with staff or contractors using BYOD (bring your own devices), where traditional security measures are often overlooked. While zero trust may reveal previously unaddressed vulnerabilities, it is essential for maintaining security as attackers relentlessly probe systems for weaknesses.

3. Supply Chain Security

As businesses become more interconnected, securing supply chains from cyber threats is increasingly critical. Security incidents involving third-party vendors have nearly doubled, highlighting the need for stronger supply chain security. Many Tier 1 suppliers now require their Tier 2 and Tier 3 partners to hold Cyber Essentials accreditation, and these certifications are becoming mandatory just to tender for their business. Industries such as aerospace, automotive, finance, banking, and the public sector have long required these standards, and many now request proof of Cyber Essentials accreditation before engaging in trade. Do not miss out on these opportunities—our team has already helped numerous clients achieve Cyber Essentials and Cyber Essentials Plus accreditations, securing contracts in these key sectors.

4. Cloud Security

The continued adoption of cloud services requires advanced 'cloud-native security measures'. Organisations must ensure their cloud environments are secure, scalable, and resilient to cyber threats. A common misconception is that data in the cloud is inherently safe—but how do you access your cloud data? If it’s just a password, and one you reuse elsewhere, your cloud services are just as vulnerable as on-premise systems. That is why multi-factor authentication (MFA) is essential. While it may seem inconvenient, MFA provides an extra layer of protection that is critical to keeping your data secure.

Surprisingly, many still do not enable MFA on their Microsoft 365 accounts or set up proper backups of their 365 data, often assuming Microsoft automatically handles this—it doesn't. We can help you implement these essential security measures easily and affordably.

5. Cyber Hygiene

Strengthening cyber hygiene practices will be essential for organisations. Regular system updates and vulnerability scanning, comprehensive employee training, and stringent access controls are key to maintaining a robust security posture. Secure, regular backups across multiple locations are also critical in defending against attacks. The rise of Ransomware-as-a-Service (RaaS) has made it easier for even less technically skilled ‘threat actors’ to launch attacks using pre-built ransomware kits. This trend highlights the growing need to address human vulnerabilities, as employees often represent the weakest link. Investing in security awareness training can significantly reduce the risk of such breaches.

In conclusion, staying ahead of these cyber security trends is essential for organisations to protect their assets and ensure business continuity in an increasingly digital world.

At Minster, we offer cyber training workshops tailored to your needs, which can be conducted quarterly, bi-annually, or annually, either in person or remotely. These sessions are highly effective for both management and staff and can also be integrated into your onboarding program to equip new employees—often the most vulnerable— with essential security knowledge.

We also assist many of our clients with their annual cyber insurance questionnaires and cyber policy creation. From awareness training to vulnerability testing, and implementing best-in-class security solutions, including Cyber Essentials and Cyber Essentials Plus accreditation, we provide comprehensive support.
