Insider threats remain one of the most persistent challenges in cybersecurity. As businesses continue to embrace hybrid work environments and advanced technologies, the risks posed by both malicious and accidental insider actions are growing. According to CyberSmart’s recent Cost of Living Report, 7% of senior leaders and decision-makers within the UK believe their employees are cyber savvy and can easily snoop on the company’s network and systems or hack into the company’s emails/messages. For Managed Service Providers like Vissensa, addressing these threats is essential to safeguarding client data and maintaining trust.
Here are key takeaways and strategies to combat insider threats in 2025:
1. Cultivate a Culture of Security Awareness
Human error remains one of the most significant contributors to insider threats. Ongoing security education is vital to mitigate this risk. At Vissensa, we prioritise:
- Regular training sessions for both employees and clients.
- Awareness programmes highlighting the dangers of phishing and social engineering attacks.
- Sharing best practices to prevent accidental data breaches.
By fostering a culture of vigilance, we can help reduce the likelihood of insider threats caused by negligence or ignorance.
2. Implement Role-Based Access Controls (RBAC)
Not everyone needs access to every system or file. Limiting access based on job roles significantly reduces the risk of data misuse. Vissensa’s approach includes:
- Defining clear access levels for employees and contractors.
- Conducting regular audits to ensure permissions align with current responsibilities.
- Promptly revoking access when roles change or employees leave.
3. Leverage Advanced Monitoring and Anomaly Detection
Insider threats often go unnoticed because they originate from trusted users. Behavioural analytics and anomaly detection tools are crucial to identifying suspicious activities, such as:
- Accessing sensitive data outside normal work hours.
- Downloading unusually large amounts of information.
- Unauthorised attempts to modify or delete critical files.
At Vissensa, we use advanced monitoring solutions to provide real-time insights into user behaviour and flag potential threats before they escalate.

4. Adopt the Principle of Least Privilege (PoLP)
Minimising access to sensitive systems and data is a cornerstone of effective cybersecurity. PoLP ensures that employees only have the permissions necessary to perform their tasks. This approach involves:
- Establishing strict protocols for granting access.
- Regularly reviewing and updating permissions.
- Ensuring temporary access is revoked promptly after its purpose is fulfilled.
5. Utilise Data Loss Prevention (DLP) Tools
DLP technologies are instrumental in preventing data leaks. By monitoring data flows and blocking unauthorised transfers, MSPs can safeguard sensitive information. Vissensa employs DLP solutions to:
- Track the movement of critical data across networks.
- Prevent unauthorised file sharing or external uploads.
- Provide detailed reports on data access and usage.
6. Develop Robust Incident Response Plans
Even with preventive measures in place, insider threats can occur. Being prepared to respond swiftly and effectively is crucial. At Vissensa, we emphasise:
- Creating comprehensive incident response plans.
- Conducting regular simulations to test these plans.
- Ensuring clear communication channels during incidents to minimise damage.
