A study by the email security firm Tessian found that 40% of employees admit to taking data with them when they leave a job. According to the Tessian report, 53% of employees who took data said they did so because they worked on the document and therefore believed it belonged to them.
In the landscape of modern cybersecurity, small business owners have traditionally focused their defences on the "digital front door," investing in firewalls and security software. However, as the workforce becomes more mobile and data becomes easier to move, a new insider risk is becoming prevalent.
Protecting this intellectual property, such as client lists, proprietary designs, pricing strategies, and strategic plans, from accidental leaks or intentional theft by departing employees has become a priority. Specialised tools, like Mimecast Incydr, are designed to monitor data movement without interrupting productivity.
Unlike traditional Data Loss Prevention (DLP) tools, which often use "block-and-stop" methods that can frustrate staff and hinder legitimate work, Mimecast Incydr focuses on visibility. It has the ability to distinguish between everyday collaboration and high-risk activity.
For a small business, a security tool is only as good as the time required to manage it. Rather than bombarding a manager with thousands of alerts for minor file movements, the Incydr proactively prioritises events that look like actual theft or significant mistakes.
By monitoring when files are moved to personal cloud storage, unauthorised USB drives, or personal email accounts, business owners can intervene before the data actually leaves the building.
Beyond the immediate protection of files, a data breach involving client information can result in legal costs and reputation damage.
Data loss from inside is a significant issue with multitude of consequences. To protect your business, get in touch.
