How to secure remote and hybrid workers

Marcus Whitfield · Infrastructure Consultant10 min read

Hybrid working is now normal, but most security setups were built for a world where everyone sat behind one office firewall. The moment work spreads to kitchen tables, coffee shops and home routers, that old perimeter has holes in it. The good news: securing remote and hybrid workers does not mean locking everything down or buying a wall of products. It means getting a handful of fundamentals right, in a way staff barely notice. Here is the practical checklist, in priority order.

Accept the office walls have moved

The starting point is a mindset shift. For years, security assumed a trusted inside and a hostile outside, with a firewall between them. When your people work from anywhere, the 'inside' is wherever they happen to be, and the device in their bag is now the real perimeter.

That is why the modern approach focuses on protecting identities and devices rather than a building. The principle behind it - never assume something is safe just because it once connected from the right place - is called Zero Trust, and we explain it without the buzzwords in Zero Trust made simple. You do not adopt it all at once; you work towards it one fundamental at a time, starting below.

Lock down identity first

When the perimeter is gone, the login becomes the front door, and a password alone is a door with no lock. Securing who can sign in is the highest-value thing you can do for remote workers, and it is mostly quick.

  • Turn on multi-factor authentication everywhere - email, file storage, every business app. It is the single biggest defence against stolen passwords, and our guide to rolling out MFA walks through doing it without chaos.
  • Use a password manager so staff have strong, unique passwords they do not have to remember or reuse - see password managers for business.
  • Apply least privilege: people get access to what their role needs, no more, so one compromised account opens fewer doors. Our identity and access management team handles this at scale.

Secure the device, not just the door

A locked door is no help if the room behind it is already on fire. Remote devices are exposed to home networks, family use and dodgy downloads, so each one needs to defend itself wherever it is.

Three things do most of the work: keep operating systems and apps automatically updated, because unpatched software is how most attacks get in; run proper endpoint protection that can detect and respond to threats rather than just scan for known viruses - the difference is covered in EDR vs antivirus; and turn on full-disk encryption so a laptop left on a train is a lost asset, not a data breach. For company-owned devices, central management lets you enforce all of this and wipe a lost machine remotely.

Give them a safe way in to what they need

Remote staff still need to reach company systems, and how they do it matters. If everything they use already lives in cloud apps protected by MFA, they may need very little extra - the apps are reached securely over the internet already.

If they need to reach systems that still live in your office - a file server, a database, a legacy application - give them a protected route rather than exposing those systems to the internet. Traditionally that is a VPN, explained in what a VPN is for business; increasingly it is the more granular Zero Trust approach, where each person connects to one specific application and proves who they are every time. The right choice depends on where your data lives, which is exactly the question our Zero Trust work starts from.

Make the human the strongest link

Technology stops a lot, but the most common way into a business is still a convincing email aimed at a person, and remote workers - distracted, isolated, off the office rhythm - are prime targets. No tool fully closes that gap; trained people do.

So invest in the human layer: regular, short security-awareness training so staff can spot a phishing attempt, and a no-blame way to report anything suspicious quickly. Pair that with good email security to filter the obvious attacks before they ever land. Our security awareness training is built for exactly this - turning the person at the kitchen table from your biggest risk into your most reliable sensor.

Write it down and make it the norm

All of this only sticks if it is clear and consistent. A short, readable remote-working policy - what devices are allowed, what is expected, who to call when something feels wrong - does more than a thick handbook nobody reads.

Set the baseline once: MFA on, devices encrypted and updated, a safe route to internal systems, people trained, and a simple policy everyone has seen. Review it as the business changes. Get those fundamentals in place and hybrid working stops being a security worry and becomes just how you work - which, given that a single breach can be existential for a small firm, is the whole point. If you would rather not assemble it piece by piece, a managed approach via our cyber security services brings the lot together.

Key takeaways
  • The perimeter has moved to wherever your people are - secure identities and devices, not a building.
  • Lock down identity first: MFA everywhere, a password manager, and least-privilege access.
  • Secure each device itself - auto-updates, proper endpoint protection (EDR) and full-disk encryption.
  • Give safe access to internal systems via VPN or Zero Trust; cloud apps with MFA often need little extra.
  • Train people to spot phishing and report it - the human is the most-targeted way in, and training makes them your best sensor.
Frequently asked

FAQs — How to secure remote and hybrid workers

Where to start

What's the single most important thing for remote security?

Multi-factor authentication, by a distance. Most remote breaches start with a stolen or guessed password, and MFA stops the vast majority of those even when the password is known. If you do only one thing this week, turn MFA on across email and every business app.

Do staff need a VPN to work from home securely?

Only if they need to reach systems that still live in your office, like a local file server or legacy app. If everything they use is in cloud services protected by MFA, a traditional VPN may add friction without much benefit. The right answer depends on where your data actually lives.

Devices and people

Is it safe to let staff use their own laptops and phones?

It can be, with guardrails. At minimum require encryption, automatic updates, MFA and endpoint protection, and keep company data inside managed apps you can wipe if a device is lost. Personal devices raise the stakes, so a clear policy and some central control are essential.

How do we stop home workers falling for phishing?

Combine filtering with training. Good email security blocks the obvious attacks, but the convincing ones get through to people, so short regular awareness training and an easy, no-blame way to report suspicious messages do the heavy lifting. Remote, isolated staff are prime targets, so this matters more, not less.
