Quantum Group Security: six specialist brands, one place to start.
Quantum Group Security owns and runs six specialist brands covering SOC 2 readiness, penetration testing and PCI DSS. Tell us what you need and we will point you at the right one, or tell you honestly that you need somebody else.
Four questions, about a minute. No phone number asked for, and no sales call.
The teams our Quantum Group Security brands serve
Security, engineering and finance teams come to Quantum Group Security when an auditor, a customer or a bank has asked them for something they do not yet have.
Logos are the property of their respective owners.
What Quantum Group Security actually is
Quantum Group Security is a holding company, explained here without the jargon. So if you have never dealt with one before, this section is the whole thing in four short paragraphs.
Quantum Group Security is a holding company. That means it owns other companies rather than doing the work itself. Think of it as the company that owns a set of specialist workshops, where each workshop does one job properly instead of every job adequately.
The six companies inside Quantum Group Security are the ones that do the work. One prepares businesses for a SOC 2 audit, another runs penetration tests, and a third handles PCI DSS readiness. Each has its own name, its own website and its own focus. A business asking about card payments should not have to wade through penetration testing content.
So Quantum Group Security exists to make that choice simple. You describe the problem once, and we route you to the brand that handles it. However, if none of them fit, we say so and point you elsewhere rather than selling you the nearest thing we happen to own.
Everything Quantum Group Security does sits in one field, because focus is the point. That field is helping companies prove to somebody else that their security is in order. That somebody is usually an auditor, an enterprise customer, or a bank.
Six brands under Quantum Group Security
Each Quantum Group Security brand is a separate company with a separate contract. So pick the one that matches your situation, or send the form at the bottom and we will pick for you.

Visit WinslowHow Quantum Group Security delivers the work
Quantum Group Security is direct about this, because it is the question every serious buyer asks second, right after what it costs.
Quantum Group Security uses specialists, not generalists
Every Quantum Group Security engagement is carried out by practitioners who do that one thing full time. So penetration tests go to testers holding OSCP or CREST. Compliance work goes to people who have sat through the audits.
One Quantum Group Security contract, one fee
You contract with a single brand in the group. That means one agreement, one fixed fee agreed before work starts, and one person who answers when you write. Also no chains of subcontractors to chase.
Where Quantum Group Security steps back
Formal audits and attestations are performed by independent firms, never by Quantum Group Security. Our brands prepare you and hand you over, because that separation is a rule in the standards and it protects you.
What Quantum Group Security will not do
Quantum Group Security does not sign audit reports, issue attestations, or certify anybody. We also do not promise you will pass. Any firm that promises that is either confused about the rules or hoping you are.
What Quantum Group Security means for your contract
A Quantum Group Security structure sounds reassuring, but what actually matters is who you contract with and who is answerable if something goes wrong. So here is the honest version.
| Question | The answer |
|---|---|
| Who do I contract with? | The brand you engage, not the holding company. The entity name is on the agreement, and we will tell you plainly before you sign. |
| Who is accountable? | That same brand. It scopes the work, manages it, runs quality assurance and remains your point of contact throughout. |
| Who does the actual work? | Vetted specialist practitioners under contract to that brand, working under its project management and confidentiality agreements. |
| Who signs the formal audit? | An independent firm, never us. For SOC 2 that is a licensed CPA firm; for PCI DSS it is a Qualified Security Assessor. |
| Does the group make it safer? | It means shared standards and one place to start. It does not, on its own, make any company bigger or better, and we will not pretend otherwise. |
Standards every Quantum Group Security brand holds to
Five rules apply across every Quantum Group Security brand. They are written down because they are the things buyers get burned on most often.
Prices in the open
Quantum Group Security brands publish real market ranges rather than hiding everything behind a form. So you should be able to budget before you talk to anybody.
Scope in writing, both ways
What is included and what is excluded, agreed before the work begins. Vague edges are how compliance budgets drift far over.
You meet the practitioner
You are told who is doing the work and what they hold before the engagement starts, but never after the invoice.
No guarantees of a pass
Independent assessors reach their own conclusions. We commit to preparation and evidence, never to somebody else's verdict.
We say when it is not us
If your problem sits outside what Quantum Group Security does well, we say so. Then you get pointed at someone better. Although that costs us a job, it keeps the reputation.

Questions about Quantum Group Security
What does Quantum Group Security actually do?
Quantum Group Security owns and runs six brands that help companies prove their security is in order. However, the group itself does not deliver engagements. It sets the standards the brands work to. It also routes you to the right one when you are unsure.
Which company would I be contracting with?
The brand you engage, not the holding company. The legal entity is named on the agreement and we will tell you before you sign. If a group is ever vague about that, treat it as a warning.
Do you perform the audits yourselves?
No, and we are not permitted to. A SOC 2 report is signed by a licensed CPA firm, and a PCI DSS report by a Qualified Security Assessor. Our brands prepare you for those examinations and stay alongside you while they run.
Why does Quantum Group Security run six brands instead of one?
Because the buyers are genuinely different. Somebody with a PCI deadline from their bank needs one conversation. Somebody whose enterprise customer wants a SOC 2 report needs another. So separate Quantum Group Security brands let each one be written for the person actually reading it.
Can Quantum Group Security guarantee we pass?
No, and walk away from anyone who says otherwise. The assessor reaches an independent conclusion. What we commit to is that the gaps are closed and the evidence is ready before they arrive.
How quickly does Quantum Group Security reply?
Usually within one business day, in writing, by email. There is no phone number on the Quantum Group Security site by design, because four written answers tell us more than a discovery call would.
What if none of the six brands fit?
We will tell you plainly and point you towards someone who does that work properly. It costs us the job, but a bad fit costs both of us more.
Tell Quantum Group Security what you need
Four answers is all Quantum Group Security needs to work out which brand fits, or whether you would be better served somewhere else entirely.
