The shift to remote and hybrid work has fundamentally changed the corporate attack surface. Employees who connect from home networks, personal devices, and public Wi-Fi create a dramatic increase in the number of possible entry points for attackers. Security teams need to adapt their strategies accordingly.

The new attack surface

When the workforce moved to home offices, the network perimeter all but dissolved. Every employee's home became an extension of the corporate network, often without the same security controls found in the office. VPNs that once seemed sufficient have turned out to be both a bottleneck and a weak point.

The biggest threats to remote employees

• Phishing attacks: Without on-site IT support, remote employees are more vulnerable.
• Insecure home networks: Default router credentials and outdated firmware create easy entry points.
• Shadow IT: Employees turn to unapproved apps to close productivity gaps.
• Credential theft: Reusing passwords across personal and work accounts is still widespread.

Building a framework for secure Remote Work

A resilient security strategy for Remote Work starts with identity. Multi-factor authentication (MFA) should be mandatory for every user who accesses company resources. Combine this with Endpoint Detection and Response (EDR) on all devices and a Secure Access Service Edge (SASE) architecture that replaces outdated VPNs.

Remote Work is here to stay, and so are the security challenges it brings. Companies that build security into their remote work strategy from the start, rather than bolting it on afterward, are best positioned to protect their people and their data.
