Secure remote work comes down to four things: a managed and updated device, strong sign-in with multi-factor authentication, a trusted network, and encrypted traffic whenever you leave your home network. No setup is perfectly safe, but these layers remove most of the everyday risk. This guide covers each layer, when a VPN belongs in the mix, and what teams should put in place.
TL;DR
- No place is 100% safe, so aim to cut risk in layers: a managed device is the best option, then MFA, updates and a trusted network.
- Public Wi-Fi is the weak point. The NSA advises a VPN to encrypt traffic on public networks.
- Secure your home router: change default passwords and use WPA2 or WPA3.
- Teams should treat identity as the perimeter and protect APIs with rate limits, MFA and encryption.
- A VPN is one layer, not a cure-all. Pair it with HTTPS, patching and sensible habits.

What secure remote work actually means
Remote work security is the set of policies, controls and tools that keep company data safe when people work outside the office. It covers the device in your bag, the network you connect to, the accounts you sign in with and the way your employer manages access.
Can you be completely secure? No. KU Information Technology states that no place is 100% safe from cybersecurity threats. The goal is to make an attack hard, limit the damage if one succeeds, and spot problems early.
That framing helps in practice. Instead of hunting for one perfect tool, you stack modest protections so a single mistake does not expose everything.
The main risks when you work away from the office
Public Wi-Fi and fake hotspots
Hotels, airports and cafes are where most travelers get exposed. The NSA warns that data sent over public Wi-Fi is vulnerable to theft or manipulation, that a password-protected network may still not encrypt your traffic, and that attackers can set up fake "evil twin" access points to capture what you send.
NIST's National Cybersecurity Center of Excellence adds a subtle point: even when an app encrypts its data, an attacker can still see the domains, IP addresses and services your device connects to. That information can be used to stage adversary-in-the-middle attacks.
Unmanaged devices and shared computers
KU's guidance calls public computers and open Wi-Fi big security risks. A personal laptop with no patching, or a hotel business-center PC, can leak credentials in minutes.
Your home router
At home, the router is yours to look after. The Canadian Centre for Cyber Security notes that routers not supported by the organization are the user's responsibility, and that outdated firmware can open users up to attacks.
Shoulder surfing and physical exposure
Work-from-anywhere setups raise the risk of leaks even in organizations with strong policies. Sensitive data on screens can be seen by others, and photos of screens are easy to take. Use a privacy screen, keep your device in sight and lock it when you step away.
Travel abroad
When you cross borders, the exposure grows. The Canadian Centre for Cyber Security warns that threat actors can use eavesdropping devices such as IMSI catchers to target mobile devices, track location and intercept communications.
Eight habits that cover most of the risk
- Use a managed device when you can. Canadian guidance advises working only from corporate devices assigned by your employer where possible.
- Lock the device with a PIN, fingerprint or face ID. NIST's telework guidance recommends enabling PIN, fingerprint or facial ID on personal devices.
- Turn on multi-factor authentication for email, cloud tools and the VPN itself.
- Keep everything patched. Operating system, browser, apps and router firmware all count. Also keep the firewall and anti-virus switched on.
- Check your Wi-Fi security. NIST suggests confirming your Wi-Fi uses WPA2 or WPA3.
- Change default router passwords and restrict administrator access, as the Swiss Federal Office of Communications advises.
- Prefer your phone's hotspot to public Wi-Fi. The Swiss office recommends creating your own hotspot with a strong password, and the NSA suggests a mobile hotspot or a VPN for extra security in cafes and airports.
- Report anything odd. Strange prompts, unexpected logouts or lost devices go to your help desk or security team straight away.
When a VPN belongs in your setup
A VPN encrypts the traffic leaving your device and sends it through a protected tunnel. NIST's NCCoE explains that a VPN can ensure all communication to and from applications is encrypted before it leaves the device, while HTTPS protects individual sites. The two work together against eavesdropping.
The NSA goes further for public networks, strongly advising a personal or corporate VPN and sticking to HTTPS sites. North Carolina's IT department says a VPN may be necessary when accessing files, handling sensitive information or using certain websites.
A quick decision guide
| Situation | Sensible step |
|---|---|
| Hotel, airport or cafe Wi-Fi | Use a VPN, or tether to your phone |
| Home network, updated router | Strong Wi-Fi password, WPA2/WPA3, MFA |
| Travel abroad with a work laptop | Company-approved device, disk encryption, MFA, VPN |
| Accessing company files or sensitive data | Use the VPN your employer requires |
| Shared or public computer | Avoid for work |
What a VPN does not do
A VPN protects data in transit. It does not stop phishing, fix an unpatched laptop or replace MFA. CISA notes that vulnerabilities such as network sniffing can still exist even with a VPN, and that users should get explicit authorization from their organization before doing business in public settings. Treat the VPN as one layer in the stack and follow your employer's policy.
What teams should put in place
Make identity the perimeter
When staff are spread out, there is no office network to hide behind. Industry research describes user identity as the new security perimeter, protected with MFA, device health checks and least-privilege access. Give each person only the access their role needs.
Adopt zero trust thinking
CISA's joint guide describes zero trust, as defined by NIST SP 800-207, as no user or asset being implicitly trusted, with every user, device and application reauthenticating throughout each transaction. The same guide urges organizations to assess their own needs and security posture before choosing a solution rather than copying a one-size-fits-all model.
The UK's NCSC describes good zero trust network access as limiting application exposure and restricting lateral movement, so an incident has a small blast radius.
Encrypt remote access end to end
TechTarget's guidance says all remote access traffic should be encrypted end to end, and that teams should review traffic flows to find communications passing unencrypted between remote access tools and internal systems.
Protect APIs and cloud services
Developers and ops teams depend on APIs, and remote work widens their exposure. NIST's API protection guidance says runtime protections should include encryption in transit, authentication and authorization, request validation and rate limiting. It also recommends account lockouts after repeated failed logins, MFA to prevent account takeover, and bot detection.
Handle monitoring fairly
Many employers add monitoring tools to protect data. The UK's ICO says oversight should be reasonable and proportionate, with people told in advance, and documented in policy. Canada's privacy commissioner says employers should limit collection to what is necessary and restrict access on a need-to-know basis. Rules differ by country and state, so check the law where your staff work. For an audit trail, the American Bar Association's checklist suggests documenting who accessed data, when and why.
A simple remote security policy to start from
A short written policy beats a long one nobody reads. Cover these points:
- Approved devices and who manages them
- MFA required on every work account
- Update and patch expectations, including home routers
- When to use the VPN (always on untrusted networks)
- Rules for public places: screen privacy, no shared computers
- How and where to report a lost device or suspicious activity
- What the company monitors, and why
Review it every year, and after any incident.
Our perspective
We built Lockshield VPN around a simple idea: protection should be quick to start and easy to keep using. People who travel for work do not have time for a long setup before a hotel Wi-Fi login or an airport lounge call.
That is why we focus on fast deployment, straightforward configuration and strong encryption for public network environments. Our service supports iOS, Android, macOS, Windows, Linux and TV, and works with third-party and native VPN clients. For teams running Linux, we designed native support to fit business and professional integrations.
We also think billing should be predictable. You pay once for a pre-paid period, with no subscription and no auto-renewal, so a team can add or drop access as projects and trips change.
A VPN is never the whole answer. We see it as the layer that makes every other habit safer when you are away from a trusted network.

FAQ
Is it possible to be 100% secure when working remotely?
No. No place is completely safe from cyber threats. You can lower the risk a great deal with a managed device, MFA, updates, a trusted network and encrypted traffic, and by reporting anything unusual quickly.
Do I need a VPN to work from a cafe or airport?
The NSA recommends a personal or corporate VPN on public Wi-Fi, along with HTTPS-only browsing. A phone hotspot is another good option. Follow your employer's rules too, since some require approval before you work in public.
Is a VPN enough to keep company data safe?
No single tool is. A VPN encrypts data in transit, but you still need MFA, patched devices and safe habits. Teams should add least-privilege access and zero trust principles on top.
Can my employer see what I do on a work device?
Often they can, depending on the tools and local law. Guidance from the UK ICO says employers should tell staff about monitoring in advance and keep it proportionate. Read your company's policy and ask HR if it is unclear.
