The Importance of Acting as if Your Business Has a CISO—Even When It Doesn’t
In today’s digital landscape, cybersecurity is no longer a luxury or an afterthought—it’s essential. Yet, many small to medium-sized businesses (SMEs) across the UK struggle to keep up with the pace of cybersecurity requirements, often due to budget limitations or a lack of specialised expertise. Large enterprises typically employ a Chief Information Security Officer (CISO) to lead and manage their security strategy, but most SMEs can’t afford to bring in a full-time CISO. However, even if your business doesn’t have a CISO by title, it’s critical to act as if it does.
The CISO’s role is to protect an organisation’s assets, data, and intellectual property (IP) by managing risks, implementing security policies, and ensuring compliance. But in an SME, without a designated security leader, it’s often up to business owners and IT managers to adopt a security-first mindset and put measures in place that safeguard both digital and physical assets.
Why SMEs Need a “CISO Mindset” Now More Than Ever
The statistics are alarming. According to the 2023 UK Cyber Security Breaches Survey, 32% of businesses reported cyber attacks or breaches in the past year, with small businesses often targeted due to weaker security defences. Additionally, nearly 48% of these attacks involved phishing, showing that cybercriminals are aware of and actively exploiting these gaps. For SMEs, a single breach can be devastating, causing significant financial and reputational damage, as well as potential loss of customer trust.
How Microsoft 365 and Entra Can Support CISO-like Security for SMEs
For businesses using Microsoft 365, a powerful suite of built-in tools is available to help secure data and maintain compliance. Microsoft Entra, Microsoft’s identity and access management solution, further enhances security by providing seamless, robust identity protection and access control.
1. Identity Protection and Multi-Factor Authentication (MFA):
With Microsoft Entra, businesses can implement multi-factor authentication (MFA) for all users, making it significantly harder for attackers to gain access. According to Microsoft, enabling MFA can prevent over 99.9% of account compromise attacks. SMEs can use conditional access policies to restrict access based on location, device health, and user risk levels, enabling a secure yet flexible work environment.
2. Data Protection and Loss Prevention:
Microsoft 365 offers built-in tools like Data Loss Prevention (DLP) policies, which help businesses identify and manage sensitive information. DLP policies can prevent users from inadvertently sharing sensitive data, such as personal information or IP, outside the organisation. For example, DLP alerts can notify users if they try to email confidential data outside the business, providing an extra layer of protection against accidental data loss.
3. Secure Collaboration and Document Control:
SMEs rely heavily on collaboration tools, but without the right policies in place, sharing documents can open up security risks. Microsoft 365 enables secure sharing options, allowing users to specify who can access documents and apply expiration dates on shared files. With Information Rights Management (IRM), businesses can even control whether recipients can print, forward, or copy data.
The Role of Good Policy Design in Cybersecurity
Security policies are the foundation of a strong security strategy, especially for businesses without a dedicated CISO. A well-designed policy not only sets standards but educates employees on best practices, creating a security-conscious culture within the organisation. Here are a few key areas to consider:
1. Access Control Policies: Define who has access to what. Using Entra’s identity governance, businesses can enforce “least privilege” access, ensuring employees only have access to the information they need to do their job. This prevents unnecessary access and minimises the risk of data exposure.
2. Acceptable Use Policies: Outline acceptable behaviours when using company devices or networks. By establishing clear rules on acceptable and unacceptable actions, you can reduce the likelihood of risky behaviours that could lead to breaches.
3. Incident Response Plans: Even without a CISO, every business should have a documented process for responding to security incidents. Incident response plans guide you through the steps to contain, investigate, and remediate breaches. By practising these plans through regular “fire drills,” staff can respond effectively in the event of an actual breach.
4. Regular Security Training: Employees are often the first line of defence—and the most vulnerable point in an organisation’s security. Regular cybersecurity training can educate staff on recognising phishing attempts, using strong passwords, and following best practices.
Building a Security-First Culture Without a CISO
While technology solutions like Microsoft 365 and Entra can bolster security, creating a security-first culture is equally important. Business owners and IT leaders can champion security by integrating it into daily operations. Security should be an ongoing conversation, not a one-time task. Here are a few ways to promote a security-first culture:
• Lead by Example: If leadership prioritises security, employees are more likely to follow suit. Leaders should regularly discuss security topics and remind employees of their role in protecting the organisation.
• Make Security Easy: Implementing policies that work in the background or are easy to follow encourages compliance. For example, make MFA mandatory, but ensure employees understand how it protects them and the company.
• Reward Security-Conscious Behaviours: Recognise employees who demonstrate good security practices, such as reporting phishing attempts or following data protection protocols. This reinforces positive behaviour and builds awareness.
Cybersecurity for SMEs: The Bottom Line
Operating without a CISO doesn’t mean operating without cybersecurity. By acting as if you have a CISO—making strategic decisions, implementing robust policies, and using the right tools—you can create a secure environment that protects your business from evolving threats. Microsoft 365 and Entra provide the capabilities SMEs need to secure their data, identities, and communications, giving business owners peace of mind.
Cybersecurity is no longer an issue that only affects large corporations. For SMEs in the UK, developing a CISO mindset could be the difference between a resilient business and one vulnerable to cyber threats. With practical, policy-driven approaches and the right technology, every SME can lay a strong foundation for digital security—even without a CISO.
