Cyber security company — a firm that protects your business’s IT

A cyber security company is a specialist firm that protects your IT, networks and data, helping you meet Cyber Essentials and legal duties — for example reporting personal data breaches to the ICO within 72 hours (ICO guidance) and running incident response.

First week

In the first week after you engage a cyber security company you should expect a short, targeted discovery: inventory of critical systems, an attacker-risk check on email and remote access, and an agreed immediate-action list. The supplier will prioritise basics that stop the common attacks — patching, strong passwords, firewall configuration and multi-factor authentication (MFA) on admin accounts. Good suppliers will deliver a short written record of what they checked, what they fixed right away, and any urgent gaps that need funding. Do not accept vague busywork: ask for a clear list of what changed and a short plan for next steps. A useful quick deliverable at this stage is a simple emergency contact and incident escalation procedure so your senior lead knows who to call if something happens overnight.

First month

By the end of the first month the company should have moved from triage to stabilisation. Expect these tangible outcomes: a basic patch schedule, enforced MFA across critical users, email protection (spam and phishing filters), and at least one staff security briefing. Many firms also suggest Cyber Essentials as a next step because it formalises those basics; if certification is on the table the supplier will help you scope what needs doing.

What to check in writing (ask for these in the proposal):

  • Clear list of systems covered (servers, cloud services, endpoints).
  • Definitions of response times for an incident.
  • Pricing model and what is chargeable outside the agreement.

The month-one review is also the right time to decide whether to keep the supplier on an ongoing managed basis or move to project work. If you want a quick internal reference, see Aurora’s cyber security overview for typical service groupings and responsibilities.

First quarter

After three months the relationship and the technical posture should be measurable. You should have a regular patching cadence, logs feeding a monitoring tool, and at least one desktop-to-server backup routine tested. The supplier should provide a short report showing improvements (fewer failed backups, blocked phishing attempts, closed vulnerabilities) and a roadmap for the next quarter. This is the right moment to ask for a tabletop exercise — a low-cost simulated incident that tests communications and roles. Useful outputs from a quarter review:

  • A prioritized risk register with owners.
  • An incident response runbook tailored to your business.
  • A training plan for staff that addresses the most common phishing themes.

Deliverables matter: if the supplier cannot show measurable change in 90 days, question whether they are the right fit.

First year

At 12 months you should see sustained improvement and clearer cost predictability. Aim to have: annual review of risk and controls, documented policies (access control, data retention), and either Cyber Essentials accreditation or a plan to reach it. A full-year engagement should also cover supplier management: proof that third-party services you use are configured securely and contractual security requirements are in place. Budgeting-wise, expect to move from reactive hourly costs to a steadier managed service or project schedule; that predictability is often the business case for retaining a specialist. A sensible ask for year-end is a one-page executive summary you can share with the board or your accountant showing reduced exposure and compliance steps taken.

What to watch for next

After the first year, shift focus from fixed tasks to resilience: regular testing of backups, scheduled penetration tests, and a clear plan to maintain staff training as people join and leave. Keep an eye on supplier transparency — you want monthly or quarterly metrics and an itemised invoice. If major cloud services change their pricing or security model, expect to re-scope the agreement. Finally, make sure your cyber insurance (if you buy it) reflects the technical controls you have in place; many policies require evidence of things like MFA and tested backups.

FAQ

How quickly must I report a personal data breach to the ICO?

You must report certain personal data breaches to the ICO within 72 hours when feasible; see the ICO’s reporting guidance linked earlier for details on exceptions and required information.

Can a small business afford a cyber security company?

Yes — many companies offer modular services so you can prioritise essentials first (patching, MFA, backups) and add monitoring or response later; ask for a phased proposal tied to measurable outcomes.

Will hiring a cyber security company get us Cyber Essentials certified?

They can prepare you and run the technical work required, but certification itself is issued by an accredited certification body; confirm whether the supplier will handle the application or coach your team to submit it.

How do I choose between managed service and project work?

If you want predictable monthly costs and continuous monitoring choose managed services; if you have a one-off gap (migrations, remediation) choose project work — revisit the decision at the three-month review.
