Every managed SOC provider will tell you they offer 24/7 monitoring, threat detection and rapid response. They are mostly telling the truth, which is exactly the problem: the brochures are interchangeable and the pricing is not comparable.
The things that actually separate providers are rarely on the website: whether you can reach an analyst directly at 11pm, how escalation really works, what happens when the detection is wrong, and what the contract does when you grow. Technology parity across the market is close enough that it is no longer the deciding factor.
This guide covers what a managed SOC does, the ten things to check before signing, what running one in-house genuinely costs, and how to judge a provider once they are live.
Transputec has delivered managed SOC services to UK and international organisations for over three decades, including one client relationship now in its eighth year. We have written this as the questions we would want asked of us.
What Does a Managed SOC Actually Cost?
Pricing is the question every buyer asks first and the one providers answer least clearly. Our companion guide breaks down what outsourced managed SOC services actually cost, which pricing models you will be quoted under, and what tends to sit outside the headline fee. Transputec publishes it so you can compare like for like before you shortlist.
What Does a Managed SOC Provider Actually Do?
A managed SOC gives you a security team, a detection platform and an escalation process, on subscription, without hiring any of it. The scope varies more than most buyers expect, so it is worth being specific about what is included.
| Capability | What it covers |
|---|---|
| 24/7 threat monitoring | Continuous watch across networks, endpoints and cloud |
| Incident response and management | Containment and remediation, not just an alert |
| Behavioural analytics | Detecting activity that deviates from your normal patterns |
| Vulnerability management | Identifying and prioritising weaknesses before they are exploited |
| Threat intelligence integration | External feeds mapped against your environment |
| Compliance and reporting | Audit trails and evidence for regulators |
| Endpoint detection and response | EDR across managed devices |
| Network traffic analysis | Spotting movement inside the network |
| Cloud security management | Coverage across cloud tenants and workloads |
The line to watch is incident response. Some providers alert you and stop there. Transputec’s SOC contains and remediates, which is a different service and a different cost base.
"Technology across serious providers is at parity. What differs is what happens at eleven o'clock on a Tuesday night, and whether the Transputec analyst who picks up already knows your environment."
What Should You Check Before Signing?
Ten things, in the order they usually matter.
- Expertise and experience. How long has the team existed, and in your sector?
- Technology stack. What detection platform sits underneath, and who pays for the licences?
- Compliance and certifications. ISO 27001 and SOC 2 for the provider, GDPR, PCI DSS or sector rules for you.
- Scalability. What happens to the fee if you grow 30%? Get the mechanism in writing.
- Threat intelligence. Which feeds, and how are they tuned to your environment?
- Incident response and containment. Included or billed separately? This is where quotes diverge most.
- 24/7 support. Genuine cover, or business hours with an out-of-hours answerphone?
- Cost and ROI. Which pricing model, and what is excluded?
- Customised solutions. How much tuning is done during onboarding, and is it in the fee?
- Customer references. Ask to speak to a client who has been with them more than three years.
On pricing models specifically, you will meet subscription, pay-per-use and tiered. Ask which one you are being quoted under before comparing two providers, because the same service priced three ways looks like three different businesses.
These are the questions we would want a buyer to put to Transputec, and to every other provider on the shortlist.

What Separates a Good SOC Partner From a Great One?
The people, and how reachable they are when something goes wrong.
Detection technology across serious providers is broadly at parity. What differs is what happens at eleven o’clock on a Tuesday night when something looks wrong. Transputec clients have direct access to the analysts watching their environment by phone, Teams or WhatsApp. Not a ticketing queue, not a first-line helpdesk reading from a script.
Three questions get at this quickly:
- Do clients have direct access to the analysts watching their environment, or does everything go through a helpdesk?
- How does escalation actually work, and who makes the call?
- When did the provider last visit a client in person?
That last one sounds soft. It is not. Our SOC Manager, Toni Nakovski, recently met a client face to face for the first time after eight years of working together. That client is IQPC, and the entire relationship had been built through monthly reviews, Teams calls and incident response over phone and chat. The trust was already there from years of remote delivery. Meeting in person let the relationship go deeper.
The best partnerships are built on communication, consistency, and the occasional face-to-face that keeps things grounded in reality.
What Does a Monthly Review Cover?
A good provider reviews with you every month, and the agenda tells you how seriously they take the relationship. Transputec’s monthly reviews cover threat detections and how they were handled, environment changes affecting your risk profile, threat intelligence relevant to your sector, and a forward look at where additional protection makes sense.
If a provider cannot describe their review agenda, they probably do not hold them.
What Does Running a SOC In-House Actually Cost?
More than most boards expect, because the constraint is not salary, it is the rota.
Genuine 24/7/365 cover is 8,760 hours a year. One analyst delivers roughly 1,700 productive hours after holiday, training and sickness. That means a minimum of five analysts before anyone has covered a single weekend properly, and most teams run six to avoid single-person night shifts.
An illustrative model, using the UK average SOC analyst salary of £43,220 reported by Indeed in August 2026:
| Line | Illustrative annual cost |
|---|---|
| 5 analysts, fully loaded at roughly £55,000 with employer NI, pension and training | £275,000 |
| SIEM platform licensing and tooling | Additional |
| Recruitment and replacement cost | Additional |
Fully loaded means salary plus employer National Insurance, pension and training, which typically adds 25 to 30 per cent.
Two things that model does not price. Recruitment risk: one resignation on a five-person rota leaves you uncovered while you hire, and SOC analysts are hard to replace quickly. And experience: a five-person in-house team sees only your environment, while a provider’s team sees patterns across a client base.
Outsourcing is almost always cheaper below roughly 1,000 staff. Above that the calculation gets closer and often lands on a hybrid, with an in-house team during business hours and a provider covering nights and weekends.
Where Does AI Fit, and Where Does It Not?
AI earns its place in a SOC on volume, not on cleverness.
A busy SOC generates far more alerts than any team can review by hand, and a large share are false positives. Automation triages that volume, suppresses the noise and surfaces what a human should actually look at. That is a real saving in analyst time and a real reduction in the chance that a genuine detection is missed in the queue.
What AI does not do is replace judgement during an incident. Deciding whether to isolate a compromised host in the middle of a working day is a business decision as much as a technical one, and it needs someone who understands what that host does.
Transputec’s approach is vendor-agnostic. Our SOC integrates with existing SIEMs, firewalls, cloud environments and endpoint tooling rather than requiring you to replace a stack you have already paid for. If you are exploring where automation fits more broadly, our AI consulting services team works on the same principle.
How Do You Judge a Provider Once They Are Live?
Agree the measures before you sign, because they are hard to introduce afterwards.
- Incident response time against the committed target, and what happens when it is missed
- Threat detection rate, and how many detections turned out to be genuine
- Compliance adherence, evidenced rather than asserted
- Cost-effectiveness against the in-house alternative
- Customer satisfaction, measured rather than assumed
On the last point, Transputec publishes its customer satisfaction data including Net Promoter Score. Ask any provider for theirs. A provider who measures satisfaction and publishes the result is making a claim they can be held to.
For a working example, Worldwide Flight Services described their reasoning when they invested in cyber security monitoring with Transputec.
Conclusion
Choosing a managed SOC provider is less about comparing feature lists than about working out who will actually pick up the phone when something goes wrong at an inconvenient hour.
The technology is close to parity. The pricing models are comparable once you know which one you are being quoted under. What differs is access to the people, how honestly a provider describes what is not included, and whether the relationship survives past the first renewal.
Transputec has run managed SOC services for over three decades and has client relationships measured in years rather than contract terms. Our SOC team is reachable directly, our review cadence is monthly, and our satisfaction data is published rather than claimed.

FAQs
What is a managed SOC service provider?
A managed SOC service provider gives you a security operations team, a detection platform and an escalation process on subscription, without you hiring analysts or buying tooling. Transputec’s managed SOC services cover monitoring, detection, incident response and compliance reporting.
What should I ask a managed SOC provider before signing?
Ask which pricing model applies and what happens if you grow, whether incident response is included or billed separately, what the response commitments are and what happens if they are missed, how long data is retained, and whether onboarding and tuning sit inside the fee. Ask to speak to a client of more than three years.
Is a managed SOC cheaper than building one in-house?
Usually, below around 1,000 staff. Genuine 24/7 cover needs a minimum of five analysts before nights, weekends and holidays are covered, which is a permanent cost of roughly £275,000 a year before tooling. For a breakdown of what outsourced pricing looks like, see how much a managed SOC costs.
Can a managed SOC work alongside our existing security tools?
Yes. Transputec’s SOC is vendor-agnostic and integrates with existing SIEMs, firewalls, cloud environments and endpoint tooling, so you keep the value of what you have already bought rather than replacing it.
Are managed SOC services suitable for SMEs?
Yes, and SMEs often benefit most, because a 24/7 rota is disproportionately expensive at small scale. Transputec scopes managed SOC services around what a business genuinely needs monitored. See our guide to managed SOC for mid-sized businesses.
How do I measure whether a managed SOC is working?
Agree the measures before signing: incident response time against target, detection rate and how many were genuine, evidenced compliance, and published customer satisfaction. Transputec’s customer satisfaction data is public.
