Remote Work Security: One Checklist for Employees and IT

October 18, 2026
Remote Work Security: One Checklist for Employees and IT

Remote work security starts with phishing-resistant sign-in (passkeys or app-based MFA), then managed endpoints with patching, EDR and encryption, then segmented access through ZTNA and least privilege, backed by tested backups and incident response. CISA and NIST guidance supports each layer, and we at Secure Techies can help you put them in place. Below you will find an employee checklist and the matching controls for decision-makers.

TL;DR:

  • Prioritize phishing resistant MFA for administrators and finance staff, then add single sign on and conditional access that checks each user, device, and login risk.
  • ZTNA limits access to specific applications; pilot it after enrolling devices, and protect retained VPNs with MFA, preauthentication, and strict patch controls.
  • Employees should use an authenticator app or FIDO key rather than SMS, store unique passwords in a password manager, encrypt devices, and enable automatic updates.
  • Keep backups separate from production and test restores regularly; rehearse stolen phone and compromised laptop scenarios, then revoke credentials and isolate affected devices quickly.

What are the biggest remote work risks, and how do attackers use them?

Remote work moves your work to places you do not control: home routers, shared cafés, personal phones and vendor laptops. Attackers know this, and they go after the weakest of those points first.

  • Phishing and credential theft: Email is a preferred attack vector for phishing, and it often leads to stolen logins. Social engineering sits underneath most of these attacks, including business email compromise, where a criminal poses as a boss or vendor and asks for a payment or a password.
  • Insecure Wi‑Fi: Home routers with default passwords and open public networks let attackers spy on traffic, tamper with DNS lookups and run man-in-the-middle attacks. If you travel often, Lumo eSIM Store explains how mobile data management can keep you off untrusted hotspots.
  • Unmanaged personal devices and device loss: A personal laptop with no encryption and no remote wipe turns a forgotten bag at an airport into a data breach.
  • Outdated software: Unpatched systems are an easy path for malware and ransomware. A single old browser or VPN client can give an intruder a foothold.
  • Third-party access: A contractor's compromised laptop can become a doorway into your network, and from there attackers move sideways to systems far more valuable than the first one they touched.

Notice the pattern. Most of these attacks target people and their accounts first, not firewalls. That is why identity protection comes before almost everything else in this guide.

Which technical controls should organizations put in place first?

Decision-makers get the best return by working through four areas in order: identity, endpoints, network and email. Treat access governance as the thread that ties them together.

Identity. Require phishing-resistant MFA, such as FIDO security keys or passkeys, wherever your systems support it. Put everything behind single sign-on so you have one place to enforce rules, and add conditional access policies that check the user, the device and the risk of each sign-in. If you are weighing options, our guide to passkeys versus MFA for small business walks through the trade-offs.

Endpoints. NIST guidance advises securing every telework component, treating external networks and devices as hostile, and enrolling devices in management. In practice that means:

  • Enroll every laptop and phone in MDM or EMM.
  • Deploy endpoint detection and response (EDR) on all work devices.
  • Turn on full-disk encryption.
  • Automate operating system and application patching.

Network. NIST also recommends segmenting external client devices from internal networks. Keep internal apps off the public internet, use secure DNS, and separate guest, BYOD and corporate traffic. As your team grows, SASE or SSE services can spread these protections across many locations without a pile of hardware.

Email. CISA's counter-phishing guidance points to a secure email gateway, URL and attachment inspection through sandboxing, and outbound web-browsing protections. Link rewriting adds a second look at every link at the moment someone clicks it. Hardened endpoints and MFA then limit the damage when a message slips through.

Access governance. Give people the least access they need to do their jobs. For administrators, use just-in-time and just-enough access so powerful accounts exist only when a task requires them. Review roles on a schedule, because access tends to pile up as people change jobs.

Pro Tip: Roll out phishing-resistant MFA to administrators and finance staff first. They are the highest-value targets, and protecting them removes your most damaging attack paths early.

How do Zero Trust and ZTNA differ from a VPN?

Zero Trust means no user or device is trusted by default, wherever it sits. Zero Trust Network Access (ZTNA) applies that idea to remote access. Microsoft's remote-work guidance explains that a VPN grants broad network access once someone authenticates, while ZTNA enforces least privilege, continuous verification and per-application access. The result is a smaller attack surface and far less room for an intruder to move sideways. Users usually notice better performance too, since traffic no longer funnels through one tunnel.

A practical path looks like this:

  1. Start with identity and conditional access.
  2. Enroll devices before you enforce device-based rules broadly.
  3. Pilot with a small group, fix what breaks, then expand.

You do not need to switch off your VPN overnight. CISA recommends a careful migration and lists mitigations for VPNs you keep in the meantime: MFA, pre-authentication, and strict patch and version control. For a deeper walkthrough, see our Zero Trust explainer for small business.

What should every remote employee do today?

These steps are practical to work through, and each one lines up with a control your organization should enforce. Work through them in order.

  1. Turn on strong MFA. Use an authenticator app or a FIDO key or passkey, and drop SMS codes where you can. CISA's mobile guidance recommends FIDO-based authentication for valuable accounts and avoiding SMS-based MFA.
  2. Use a password manager. Replace reused or weak passwords with long, generated passphrases, one per account.
  3. Update automatically. Turn on automatic updates for your operating system, browser and apps.
  4. Lock and encrypt your device. Enable disk encryption, set a strong passcode, and make sure remote wipe is switched on.
  5. Protect your messages. Use end-to-end encrypted messaging for sensitive topics, and review the linked devices in your messaging apps. Remove any you do not recognize.
  6. Set a PIN with your mobile carrier. It reduces the risk of SIM-swap fraud against your phone number.
  7. Be careful on public Wi‑Fi. Avoid untrusted networks, use your company's secure connection or encrypted DNS, and think twice before sharing files from a shared network.
  8. Report anything odd quickly. A suspicious email you flag promptly is less costly than one you click and report later.

Pro Tip: Check your home router once: change the default admin password, update its firmware and turn off remote administration. It is the one device every work session passes through.

Our remote work security checklist goes further for hybrid teams, and our security awareness training guide covers the habits behind it.

How should you prepare for incidents, backups and recovery?

Prevention will not catch everything, so plan for the day something gets through. Recovery speed often decides whether an incident is a bad afternoon or a lost month.

  • Keep backups separate and tested. Store copies away from production systems and run restore tests on a schedule. A backup you have never restored is only a hope.
  • Watch public-facing assets. Automate vulnerability scanning and monitoring, and feed alerts into one place so the most serious ones surface first.
  • Rehearse remote scenarios. Add a compromised home laptop and a stolen phone to your incident response plan, with clear escalation and notification steps. Our incident response plan guide is a good starting point.
  • Contain fast. Block the compromised device, revoke credentials, rotate secrets and isolate the affected network segment before you start investigating.

Why do policies and training make the technology work?

Controls fail when people do not know why they exist. A short, clear telework policy should state which devices are approved, how people may connect, how data is classified and handled, and whom to tell when something looks wrong. Require training on phishing, password habits and data handling, either annually or by role, and repeat it when threats change.

For personal devices, give employees privacy as well as protection. NIST's BYOD project shows how work profiles, application vetting and selective wipe protect company data while keeping personal data personal. Finally, audit access regularly, review roles, and keep a written roadmap for Zero Trust adoption so progress does not stall.

How do we help organizations secure remote work?

Our team supports each layer of this guide through Managed IT Services, Cybersecurity Solutions, Network Security, Backup & Disaster Recovery, and Compliance & Security Audits. We also publish practical material you can use right away, including our Microsoft 365 MFA rollout case study, which shows how a real rollout was planned. A first engagement begins with an assessment of your accounts, devices and access, followed by a prioritized roadmap and clear service expectations. Ask us for a security health check and we will map the gaps against the controls above.

Why we put identity and recovery ahead of perfect prevention

No small or mid-size business blocks every attack, and chasing that goal wastes budget on rare threats while basics like MFA go half-finished. I would rather see a company lock down sign-ins, keep devices patched and prove it can restore its data promptly. Those are measurable: how quickly you detect a problem and how fast you recover. Managed services earn their keep here, because someone is watching and patching regularly.

FAQ

How do you maintain security when employees work remotely?

Combine strong sign-in protection, managed and updated devices, segmented access and tested backups. Employees handle the daily habits, and the organization enforces the controls behind them. CISA's counter-phishing guidance adds email gateways and hardened endpoints to that list.

What is remote work security?

It is the set of practices and tools that protect company data, accounts and devices when people work outside the office. It covers identity, endpoints, networks, email and the policies that tie them together. The goal is to keep work safe wherever it happens.

Can you be completely secure while working remotely?

No setup is risk-free, and any provider who promises that is overselling. You can reduce risk a great deal with phishing-resistant MFA, patched devices and segmented access, and you can limit damage with backups and a practiced response plan.

How do you work remotely and stay secure?

Use MFA on every account, a password manager, automatic updates and an encrypted device. Avoid untrusted Wi‑Fi, and report suspicious messages quickly. Our checklist above turns these into practical steps you can work through.
