Remote and hybrid work move your security boundary from the office network to each person and each device. To keep it secure, you need strong identity controls, managed devices, patching that works anywhere, and a safe way to reach company files.
When everyone worked in one office on one network, the perimeter was easy to picture. Now your team works from home networks, hotel WiFi and vacation rentals. Laptops leave the building, credentials get typed into personal computers, and the home router may not have been updated since the internet provider installed it. This article covers what a business needs in place so remote work doesn't quietly undo its security.
The older model asked one question: is this device on our network? If yes, it was trusted. That stopped working once the network was everywhere.
The Zero Trust model asks better questions. Who is this user? Is this a known, managed device? Does this request look like normal behavior? Every access attempt is verified, whether it comes from the office or an airport lounge.
In practice, that makes multi-factor authentication (MFA) and single sign-on (SSO) the foundation of remote work security, not optional extras. Without MFA, a password stolen through phishing or a credential stuffing attack can turn into a full account takeover.
For years, a VPN was the standard answer. It creates an encrypted tunnel from the remote employee's device back to the office network, so the device behaves as if it were in the building.
The drawback is scope. Once the tunnel is up, the device can reach everything the user's credentials allow. If that device or those credentials are compromised, an attacker inherits the same broad access.
Zero Trust Network Access (ZTNA) takes a narrower approach. It grants access to specific applications based on verified identity and device health, without placing the device on the wider network. If a credential is stolen, the damage is far more contained.
For many small businesses, a well-configured VPN with MFA, device health checks and network segmentation is still a sound choice. For businesses with regulated data or more complex environments, ZTNA is often the better fit. We weigh both against each client's environment and risk.
A laptop that travels connects to unknown networks, rides home in a bag and may be used by family members after hours. Device management has to account for all of that.
Every device that touches company data, company-issued or personal under a bring-your-own-device (BYOD) policy, should be enrolled in mobile device management (MDM). That lets you enforce encryption and screen locks, keep patches current and wipe company data remotely if a device is lost or an employee leaves.
Endpoint detection and response (EDR) watches device behavior no matter which network the device is on. A laptop on home WiFi gets the same behavioral protection it would have in the office. For more background, see our EDR explainer.
Office computers get updates while they sit on the office network. Remote laptops can go weeks without them unless patching is designed for a distributed team. Remote monitoring and management (RMM) pushes updates wherever the device is connected, so a laptop that never comes to the office still stays current.
You don't control the home network, but you still carry its risk. The common issues:
When reaching company files is awkward, people find workarounds: emailing documents to personal accounts, saving them to personal cloud storage or carrying them on USB drives. Those copies are hard to track and harder to get back.
The fix is managed cloud storage that's easy to reach from anywhere. For businesses on Microsoft 365, that usually means SharePoint and OneDrive with the right permissions and access controls, set up through our Microsoft 365 support. Files stay in the managed environment, access is logged and can be revoked, and when someone leaves, their access ends with them.
Remote work brings its own compliance questions. HIPAA's workstation use and workstation security standards apply wherever patient data is accessed, so screen locks, workstation policies and controls on home devices matter. The FTC Safeguards Rule under GLBA expects a financial institution's information security program to account for the risks of remote access. PCI DSS includes requirements for remote access to systems in the cardholder data environment, including MFA.
For regulated businesses, the written security program should address the remote work environment directly rather than assume office controls carry over to a kitchen table. NerdSquad is not a law firm; confirm your obligations with your compliance counsel.
As part of our cybersecurity services, we put remote work controls in place for clients: MFA, identity and device management, EDR on every endpoint, patching that works regardless of location, and cloud storage configured for secure remote access. For clients in regulated industries, we document those controls so they support your compliance program. If you're moving from fully in-office to hybrid, we can review your setup, identify gaps and build a plan to close them before remote work becomes routine. A new employee IT security checklist is a good companion for onboarding remote staff.
