Cybersecurity

Protect your people, devices and business data.

For most small and medium businesses, cybersecurity is not a product you buy once. It is the practical work of who can sign in, how email is protected, whether laptops are updated, and whether you could recover if something got through.

NovaStak Ltd works with small and medium businesses across the UK and is based in Northamptonshire. We do not promise that any control makes you impossible to breach. The aim is to reduce everyday risk, limit the damage, and keep the business working.

If this is familiar

Common cybersecurity risks

Most trouble starts with ordinary work: a mailbox, a shared password, a laptop that never got updates. These are the gaps we see again and again.

A password is still enough to get in

Staff reuse logins. If that password leaks, email and files open with no second check.

A convincing email reaches the inbox

An invoice, a delivery note or a message that looks like IT. One click, then a scramble.

Laptops go unpatched

Updates sit in the background until a machine is slow, lost, or still holding client files years after support ended.

A leaver still has company mail

The laptop comes back. The phone and the shared mailbox do not. Access was never treated as a control.

Everyone shares an admin login

The “IT password” lives in a notebook. Nobody can say who changed what, or when.

Backups have never been restored

A job “succeeds” every night. That is not the same as getting last Thursday’s work back.

How it fits together

Layered protection

One control is not a security programme. If sign-in is tight but laptops are not updated, the risk has only moved. In practice, layers mean identity, devices, Microsoft 365 and backup working together, not a wall of products you never open.

Identity

Who can sign in, with what checks, and who still has access after they leave.

Antivirus and endpoints

Company laptops protected with antivirus and updates, set up in a known way, and easier to lock if lost.

Microsoft 365

Email, sharing and admin settings that match how the company actually works.

Backup

Copies you can restore, so a mistake or a locked file is not the end of the week.

The mix is agreed after we see how you work. We do not list certifications, insurance discounts or audit badges here until they can be shown as fact.

Who can sign in

Identity and access

Identity protection, in plain terms, is control over company accounts. Entra ID is the directory behind Microsoft 365 sign-in: it decides who gets into email and files. If it is loose, a leaked password becomes a business incident. If it is clumsy, staff share logins to get work done.

Multi-factor authentication (MFA) is a second check when someone signs in, usually on a phone. It does not make accounts perfect. It does mean a password on its own is no longer enough. Access control is the rest of the job: who has admin rights, how joiners get set up, and whether a leaver’s access actually stops.

We help you put those controls in a way the small and medium business can live with, including the exceptions people invent when the official process is too awkward.

Laptops and company devices

Endpoints, patching and device management

A mailbox on an unmanaged laptop is still company data. Antivirus and endpoint security here means the device itself: it is protected, set up in a known way, it receives updates, and it is not left running software that nobody is looking after.

Patching is the routine work of applying those updates before they pile up. Device management means a new starter can work on a standard laptop, and a lost or returned machine does not keep company files. We use Intune where company Windows PCs, and phones if you use them, need policy.

We do not roll out device management for its own sake. If a lighter approach is enough, we will say so.

Email, files and sharing

Microsoft 365 security

For most growing companies, Microsoft 365 is the office. Security configuration means tightening the settings that were left on defaults: who can send as the company, how mail is filtered, who can share a customer folder, and which admin accounts still exist.

Email security will not catch every convincing message. It does reduce the volume of junk and spoofed invoices that reach the inbox, so staff are not relying on instinct alone. Detail on day-to-day administration lives on our Microsoft 365 page. We work with these Microsoft products; this page does not claim official Microsoft partner status.

If something still gets through

Backup as a security control

Protection is incomplete if you cannot recover. An untested backup, or a copy on the same machine, is not a plan. Backup belongs in cybersecurity because ransomware, accidental deletion and a failed laptop are all ways of losing the week.

We look at what would actually stop the business, and whether those copies can be restored, not only whether a job reports success. That work sits with backup and business continuity. We do not invent recovery times on this page.

After the first controls are in place

Ongoing management

Security drifts. People join, leave, share a folder “just this once”, and laptops miss an update. Ongoing management is the routine work that keeps the controls you agreed actually in place: accounts, devices, mail settings and documentation so it is not trapped in one person’s head.

Security awareness, for us, is explaining the risks to staff in plain language, not a fear campaign. Technical controls still do most of the catching. Awareness sits alongside them so people know why MFA exists and what a suspect invoice looks like.

For most clients this is delivered as part of managed IT support, not as a separate product you never open. How we respond, and when we are available, is agreed when we take you on, not advertised as 24/7 cover.

Questions

Frequently asked questions

Will this stop every attack?

No. No honest provider can promise that. The aim is to make the easy mistakes harder, limit the damage if something gets through, and be able to recover.

Does this make us compliant with Cyber Essentials or ISO 27001?

No. Turning on technical controls is not the same as a certified audit. If you need a named standard, that is a separate piece of work with evidence, policy and an assessor, not something this page claims from a product rollout.

Do you run 24/7 security monitoring?

This page does not offer a 24/7 security operations centre or guaranteed incident response times. We help you put practical controls in place and keep them maintained. How we respond, and when we are available, is agreed when we take you on.

Do you offer security awareness training?

We help you explain the risks to staff in plain language, and tighten the technical controls that catch a lot of email-borne trouble. A full training programme is not assumed. If you want awareness work as part of a wider support agreement, we will say what that would involve.

Do we have to buy a stack of security products?

Not as a starting point. Most small and medium businesses already pay for Microsoft 365 and Windows tools they are not using fully. We look at what you have, close the obvious gaps, and only recommend extra software where it solves a real problem.

What happens in the free consultation?

A conversation about how people sign in, how email and devices are looked after, and whether you could recover if something went wrong. You should leave with a clearer next step, and no obligation to proceed.
