A small consultancy
with operational depth
Spartan Security is the trading name of Aspis Ltd — an independent UK cybersecurity consultancy. We work with small and mid-sized organisations that need credible security work without the cost or complexity of a big-name firm.
The approach
Most cybersecurity advice fails for the same reasons: it's written for organisations ten times the size of the one reading it, it leans on vendor jargon to sound authoritative, and it stops at recommendations rather than implementation.
We take the opposite view. Engagements are scoped tightly, written in plain English, and delivered by someone who's done the work in a production environment. If a control isn't going to survive contact with your operations team, we'll say so before we recommend it.
The work is grounded in three principles:
- Defensible, not theatrical. Controls that hold up to an audit and to a real incident — not ones that look good on a slide.
- Pragmatic over puristic. Standards like ISO 27001 and Cyber Essentials Plus exist to be used, not worshipped. We map controls to your context.
- Operate what you implement. A SIEM no-one tunes, an EDR no-one triages, or a policy no-one reads is worse than not having one. We deliver things you can run.
Background
The consultancy is run by a working security professional currently embedded in a UK Security & Compliance team. The day-to-day work that informs Spartan's engagements includes vulnerability management, SIEM and EDR operations, identity and access governance, compliance framework alignment (Cyber Essentials Plus, ISO 27001), and incident response playbook design.
That operational footing matters. Recommendations come from someone who runs these tools daily, not someone who reviewed a vendor datasheet last quarter. If we suggest a control, it's because we've seen what happens when it's missing.

How we engage
Spartan operates as a boutique consultancy by design. That means a small number of engagements at any one time, direct contact with the person doing the work, and no layer of account managers between you and delivery.
Most engagements start with a free scoping conversation — a 30-minute call to understand what you actually need, what you've already got in place, and whether we're the right fit. If we're not, we'll say so and point you toward someone who is.
