The short answer
If you are a seed-stage European B2B software company and an enterprise buyer has started asking for ISO 27001, SOC 2, GDPR, or AI governance proof, the best route is not always the platform with the longest feature list.
This is also a "Build in Europe" decision: whether your compliance route is designed around European buyers, European frameworks, and European startup operating constraints, or adapted from a broader US-first trust platform.
The better question is:
Who will carry the work: your founder and CTO, your internal team, a self-serve platform, or a managed partner?
Kantis is built for the small-team version of that problem. Vanta and Drata are strong, recognised platforms. Sprinto is a serious startup-friendly competitor. Delve is the most AI-native and speed-led. But if your team is small, European, ISO 27001-led, and trying to close a customer without losing CTO days, Kantis should be on the shortlist.
Quick verdict
| Option | Strongest fit | Watch-outs for a 2-20 person European startup |
|---|---|---|
| Kantis | Small UK/EU startups that want a managed, ISO 27001-led route with less CTO distraction | Narrower public footprint than the large platforms |
| Vanta | Teams that want the category leader, strong brand recognition, and a broad trust platform | Can be more platform than a tiny team wants to operate |
| Drata | Teams that want a serious trust/GRC platform and a strong auditor ecosystem | Still usually needs internal ownership to keep the programme moving |
| Sprinto | Startups and SMBs that want a support-heavy compliance platform | Strong startup positioning, but less UK/EU-specific than Kantis |
| Delve | Speed-driven teams that want an AI-native compliance experience | Verify auditor identity, accreditation, and engagement letters carefully |
That framing matters because compliance software is not the full project. A startup still needs scope, policies, risk records, evidence, employee training, internal checks, auditor coordination, and ongoing monitoring after certification.
Why this decision is different for seed-stage European startups
For a 300-person company, the answer might be simple: buy the broadest platform and let the internal security, GRC, IT, and legal teams operate it.
For a 3-person, 7-person, or 15-person startup, that assumption breaks.
The internal owner is often the CTO. The CTO is also trying to ship product, answer enterprise technical questions, support sales, fix infrastructure, and keep the roadmap alive. So the hidden cost is not only the platform subscription or the auditor fee. It is the time spent turning your actual security practices into audit-ready evidence.
Kantis is deliberately narrower than the large US-first trust platforms. It is designed for founders and CTOs who need a credible, low-distraction certification path, especially when the first requirement is ISO 27001 for a UK or European customer.

The table is intentionally not a feature-by-feature ranking. Vanta and Drata have large integration footprints and mature platforms. Sprinto is strong on startup messaging. Delve makes aggressive speed claims. Kantis wins when the buyer wants a more managed route through certification, not another broad system to operate.
Kantis vs Vanta
Vanta is hard to ignore. It has the strongest market recognition in this set, a dedicated startup programme, broad framework coverage, AI features, a large auditor ecosystem, and public claims around 20,000+ audits completed through Vanta.
That strength is also the reason Kantis is different.
Vanta is a broad trust platform. It can be a good choice if you want a recognised name, plan to build a larger trust programme, and have someone internally who can own the system. For a very small European team, the question is whether that is the right operating model.
Kantis is the better fit when you want the path managed around your actual startup: scope, policies, evidence, audit readiness, and auditor coordination, without asking the CTO to become a part-time compliance manager.
Ask Vanta:
- Who owns policy tailoring and evidence gaps internally?
- How much auditor coordination stays with our team?
- Which plan and add-ons do we actually need for ISO 27001 and SOC 2?
- Are we buying the platform we need now, or the platform we may need in three years?
Kantis vs Drata
Drata is also a serious option. It has strong continuous compliance positioning, a large customer base, a mature auditor network, and unusually clear public language around audit independence.
That makes Drata credible. It also makes it a platform-first route.
For a startup with a security owner, GRC owner, or a team ready to run a trust programme internally, Drata can make sense. For a tiny team trying to satisfy a customer requirement quickly, the risk is that the software is only part of the work. Someone still has to keep scope, evidence, policies, risks, internal checks, and auditor questions moving.
Kantis is designed for the buyer who wants that operational burden reduced. It is less about building a large internal trust function and more about getting a small European startup credibly audit-ready.
Ask Drata:
- Who will run the compliance programme day to day?
- What does support look like during Stage 1 and Stage 2 audit preparation?
- How much policy and evidence work remains with engineering?
- Is our priority a long-term GRC platform or a managed first certification?
Kantis vs Sprinto
Sprinto is probably the closest mainstream comparator to Kantis. It is startup-oriented, support-heavy, and public copy is very direct about founders and engineers being pulled into compliance work. Sprinto also publishes useful guidance on auditor accreditation and ISO 27001 certification-body selection.
So the argument is not that Sprinto is weak. It is that Kantis is more local and more focused.
Sprinto is a strong global startup platform. Kantis is a London-based, Europe-first managed route for small B2B software teams where ISO 27001, GDPR, UK/EU buyers, and auditor credibility matter. If your buyer is in London, Germany, the EU, legal, pharma, fintech, or another security-sensitive market, the local process fit can matter as much as the tool.
Kantis is the better fit when you want:
- European policy templates that match a small company, not a generic enterprise
- hands-on support through the awkward certification steps
- UK/Germany auditor-route clarity where relevant
- less internal work for the CTO
- one practical route across ISO 27001, GDPR, SOC 2, and AI readiness
Ask Sprinto:
- Which auditor or certification body will be used for our ISO 27001 certificate?
- Is the audit fee included or separate?
- How much of the process is still ours to drive?
- How much of the policy pack is tailored to a 2-10 person European startup?
Kantis vs Delve
Delve is the most AI-native competitor in this comparison. Its public positioning is speed-led: compliance in days, AI agents, automated evidence work, and a very low-friction buyer experience.
That can be attractive. It also means buyers should do careful diligence.
Delve published customer-support measures in March 2026 after public claims it described as false and misleading. Delve stated that independent licensed audit firms, not Delve, collect evidence and issue SOC 2 reports, ISO 27001 certifications, and similar attestations. It also offered complimentary re-audits, penetration tests, and auditor engagement letters.
Kantis should not turn that into a hit piece. The practical lesson is simpler: if you are choosing any fast-track or AI-native compliance vendor, ask exactly who the independent auditor is, which accreditation applies, how evidence is reviewed, and what your enterprise buyer will see.
Kantis is the better fit when you want speed, but not at the expense of process clarity. The Kantis route is intentionally explicit: Kantis prepares you, independent accredited auditors audit you, and the certificate or report comes from the auditor or certification body.
Ask Delve:
- Who is the auditor or certification body for our engagement?
- Can we speak directly with the auditor?
- What accreditation applies to the ISO certificate or SOC 2 report?
- Can we share the engagement letter with customers?
- What evidence is manually reviewed versus generated or collected by AI?
Where Kantis fits best
Kantis is not trying to be the biggest trust platform in the market. That is the point.
Kantis is worth evaluating when:
- you are a 2-20 person software startup
- you are based in the UK, EU, DACH, or selling into Europe
- ISO 27001 is the immediate requirement
- SOC 2, GDPR, ISO 42001, or EU AI Act readiness may follow
- a customer, partner, or procurement process is blocking revenue
- the founder or CTO is the likely internal owner
- you want a credible certification route without building a compliance department
The practical promise is not "magic compliance". It is a lower-distraction path: clear scope, startup-appropriate policies, evidence support, auditor coordination, and ongoing monitoring so the certificate does not become stale after it is issued.
What to ask any vendor before you buy
Use this checklist before signing with Kantis, Vanta, Drata, Sprinto, Delve, a consultant, or a DIY route.
- Who issues the certificate or report?
- Which accreditation applies?
- Is the auditor independent from the preparation work?
- Are auditor fees included or separate?
- Who owns policy tailoring?
- How much evidence work remains with the CTO?
- What happens if the auditor finds a gap?
- How are employees trained and policy acceptance captured?
- What ongoing monitoring is included after certification?
- What will enterprise customers actually see?
If the vendor cannot answer these clearly, the risk is not only audit failure. The risk is losing time during the procurement process you were trying to unblock.
Proof point: Qorelo
Qorelo used Kantis to get ISO 27001 certified in about six weeks with zero non-conformities.
That is not a universal promise. It is proof that a small, focused startup can move quickly when scope, evidence, policies, and auditor coordination are handled properly.
