Remote Work Security: How to Keep Your Business Safe When Your Team Works from Home
When your team works from the office, your security perimeter is relatively well-defined: a managed network, controlled hardware, and physical access controls. When they work from home, that perimeter expands to include every home network, personal device, and coffee shop WiFi your employees connect from. That's not a reason to prohibit remote work — it's a reason to secure it properly. Here's how.
PCI Consulting Group's managed IT services include security monitoring, endpoint protection, and proactive threat response for small and mid-size businesses.
The security risks unique to remote work
Unmanaged home networks
Home routers are rarely updated, often use default passwords, and share bandwidth with smart TVs, gaming consoles, and other devices that may be compromised. Your employee's work laptop on a compromised home network is exposed in ways it wouldn't be on your office network.
Personal device usage
When employees use personal computers or phones for work, you lose visibility and control. Personal devices often lack endpoint protection, aren't patched consistently, and may have software installed that creates vulnerabilities.
Shadow IT
Remote workers are more likely to find their own solutions when the approved tools feel slow or inconvenient — using personal Dropbox accounts for file sharing, WhatsApp for work communication, or unapproved apps for collaboration. Each of these creates data exposure your IT team doesn't know about.
Physical security
A laptop left open in a coffee shop, a screen visible to a neighbor on a video call, or a printed document left on a home desk — these physical exposures are harder to control outside the office.
The controls that matter most
-
Company-managed devices only
The single most effective remote work security measure is ensuring employees work on company-owned, managed devices — not personal computers. With MDM deployed on company devices, you can enforce encryption, push security policies, and remotely wipe a lost or stolen machine.
-
VPN or Zero Trust Network Access (ZTNA)
A VPN encrypts traffic between the employee's device and your network. Zero Trust Network Access goes further — rather than putting an employee on the network, it grants access only to the specific applications they need, from wherever they are. ZTNA is more secure and increasingly the preferred approach for modern remote setups.
-
MFA on everything
Remote access is the scenario MFA was built for. Requiring a second factor on email, VPN, and all cloud applications means a stolen password alone gets an attacker nothing.
-
Endpoint detection and response (EDR)
Antivirus is no longer sufficient. EDR tools monitor device behavior continuously — detecting and responding to suspicious activity that signature-based antivirus would miss.
-
DNS filtering
DNS filtering blocks access to known malicious domains at the network level — even on home networks, when deployed via a lightweight agent on the endpoint. It's one of the most cost-effective ways to reduce exposure.
Policies your remote team needs
- A clear acceptable use policy that defines what work data can and can't be stored locally
- Screen lock requirements — all devices must lock automatically after a short idle period
- No work on public WiFi without a VPN active
- A defined process for reporting lost or stolen devices immediately
- Clear guidance on approved tools — and which personal tools are off-limits for work
Security that doesn't get in the way
The goal of remote work security isn't to make remote work harder — it's to make it safe enough that you can offer it without taking on unacceptable risk. Done right, the controls are largely invisible to your team. PCI Consulting Group designs and manages remote work security setups for businesses of all sizes, including MDM, VPN/ZTNA, EDR, and policy development. If your remote workforce has grown but your security setup hasn't kept pace, we can help you close the gap.
