Compliance as a Service (CaaS)

Compliance software collects the evidence. A consultant builds the system that evidence is meant to prove. That’s the real difference in the ISO 27001 consultant vs software decision, and most teams only figure it out after they’ve bought one and realized they still need the other. Below, we compare what each route covers, where it breaks down, and what it costs you in time, money, and your team’s hours. Short version: software on its own works for a small group of companies. For most SaaS and tech scale-ups trying to get an enterprise deal over the line, consultant-led implementation on a compliance platform is the faster and safer path to a certificate. Quick Answer: Consultant, Software, or Both? Software-only works if you already have an in-house security lead who’s taken a company through ISO/IEC 27001 before and has the time to own the project. Consultant-only still makes sense if you run mostly on-premise or legacy systems that platforms barely integrate with. For everyone else, which means most cloud-native companies under a few hundred people, a hybrid works best: a platform to handle evidence and monitoring, and a consultant to build the management system and stand behind it in front of an auditor. Here’s why. What an ISO 27001 Consultant Handles ISO/IEC 27001:2022 is a management system standard. Clauses 4 to 10 cover how you run information security, and Annex A lists 93 controls you pick from based on risk. Almost none of it is box-ticking. Most of it comes down to judgment calls about your business, and that’s what you’re paying a consultant for. Scoping, Gap Analysis and Risk Assessment Scope is the first decision you make, and the most expensive one to get wrong. Go too wide and you’ll spend months on controls for systems no customer asks about. Go too narrow and the certificate won’t get through the procurement review it was supposed to pass. A consultant scopes around the deals you’re trying to close, runs a gap analysis, and builds a risk assessment based on your real assets and threats. That’s the document auditors dig into hardest. ISMS Documentation and Policy Writing The standard asks for a specific set of documents: the ISMS scope, information security policy, risk assessment and treatment methodology, Statement of Applicability, risk treatment plan, and evidence of competence, monitoring, internal audit, and management review. A consultant writes these around how your company works day to day, instead of how a template imagines it works. Auditors check whether you follow your own procedures, so a mismatch shows up fast. Internal Audit and Certification Audit Support You need an internal audit before certification, and Clause 9.2 says the auditor has to be objective and impartial. In a small company, the people who built the ISMS can’t credibly audit it, so most teams outsource it through ISO 27001 internal audit services. A good consultant also gets your team ready for the Stage 1 and Stage 2 audits, joins the conversations that matter, and handles corrective actions if the auditor raises nonconformities.  What ISO 27001 Compliance Software Handles Compliance automation platforms, often called GRC platforms, have changed how cloud-native companies get certified. They’re very good at the repetitive, evidence-heavy side of the work. Automated Evidence Collection and Continuous Control Monitoring The platform plugs into your cloud provider, identity provider, code repos, HR system, and device management tools, then pulls evidence on its own. It’ll flag an unencrypted storage bucket, an ex-employee who still has access, or a laptop without disk encryption. For technical controls, that saves weeks of screenshots and spreadsheet tracking. Policy Templates and Annex A Control Mapping Most platforms come with a policy library and map each control to the ISO 27001 clauses and Annex A. You get a starting point and a clear view of which controls have evidence and which don’t. Auditor Access and Ongoing Compliance Tracking Auditors can log in and review evidence themselves, which cuts down fieldwork. After you’re certified, dashboards show when controls slip between surveillance audits, so you aren’t rebuilding evidence from scratch every year. Where Each Approach Falls Short Neither route covers everything by itself. The good news is that the ways each one fails are predictable, so you can plan around them. Limits of Compliance Automation Platforms A platform can tell you a control is failing. It can’t decide your scope, run your risk assessment, write a policy that matches your operations, convince your CTO to change the offboarding process, or explain to an auditor why you excluded a control from your Statement of Applicability. Templates can also make you feel further along than you are. A dashboard at 90% can hide an ISMS that won’t survive Stage 1, because the missing 10% is the management system itself. Insider Note: The Stage 1 problem we see most on software-only projects is a risk assessment copied straight from the platform’s default risk library. The risks are generic, the scores are almost identical, and nothing ties back to the company’s own assets. Auditors notice within minutes, and it weakens the Statement of Applicability that’s built on it. The other problem is ownership. Software assumes someone inside the company will drive the project. At most startups that’s a CTO or ops lead who already has a full-time job, and the subscription renews whether the work gets done or not. Limits of a Consultant-Only Approach A consultant working without automation spends billable days on things a platform does for free, like chasing screenshots, updating evidence trackers, and collecting the same proof again before every surveillance audit. You pay more and wait longer. You also end up with a program that’s only accurate on the day it’s handed over. Once the engagement ends, the evidence goes stale and year-two surveillance turns into a scramble. ISO 27001 Consultant vs Software: Side-by-Side Comparison Factor Consultant only Software only Hybrid (consultant + platform) Time to audit readiness 3 to 6+ months Highly variable; depends on internal expertise As little as 6 weeks for well-scoped

If your ISO 27001 certificate covers all of your health and care data processing, the NHS Data Security and Protection Toolkit does two useful things with it. It marks the applicable evidence items as complete on its own, and it shrinks the scope of any independent audit to whatever your certification doesn’t already cover. A certified vendor who does the mapping properly walks into a DSPT submission with most of the technical and organizational evidence already written, already audited, and already versioned. What ISO 27001 won’t do is get you out of the DSPT. It says nothing about the NHS-specific information governance items, clinical safety, the national data opt-out, or Caldicott principles. Vendors who assume “certified means done” usually discover this in the last two weeks of June. This piece is for the founder, CTO, or ops lead at a UK health-tech company who owns compliance without being a compliance person. It covers what each framework asks for, which Annex A controls line up with which DSPT requirements, which evidence you can reuse as-is, which needs reframing around patient data, and a five-step workflow for turning an existing ISMS into a DSPT submission. One more thing on timing: NHS England published DSPT version 9 for the 2026/27 cycle on 4 September 2026, and the submission deadline is 30 June 2027. So this exercise belongs in your calendar now, not next spring. Understanding the Two Frameworks at a Glance​ What ISO 27001:2022 Covers ISO/IEC 27001:2022 is the international standard for an Information Security Management System (ISMS). It comes in two halves. Clauses 4 to 10 define the management system itself: context, leadership, risk assessment and treatment, resourcing, operation, performance evaluation, and continual improvement. Annex A lists 93 reference controls across four themes (organizational, people, physical, technological). Your Statement of Applicability (SoA) records which of those controls you apply, which you exclude, and why. An accredited certification body issues the certificate after a two-stage audit, then you keep it through annual surveillance audits and a three-year recertification cycle. The certificate covers a defined scope, and that scope statement is the first thing a DSPT assessor reads. What the NHS DSPT Requires in 2026/27 The Data Security and Protection Toolkit (DSPT) is NHS England’s annual online self-assessment for every organization that touches NHS patient data or systems. It’s a contractual requirement under the NHS Standard Contract. Your published status (“Standards Met”, “Standards Exceeded”, “Approaching Standards”, “Standards Not Met”) is publicly searchable, so procurement teams and prospective NHS customers do look it up. The Toolkit isn’t one assessment. NHS England tailors it by organization category, and your category decides which assertions you answer and whether you need an independent audit. Version 9 came out on 4 September 2026. The Category 1 view is aligned to CAF version 4.0, and the whole thing closes on 30 June 2027. Insider Note: Most health-tech SaaS vendors are Category 3, not Category 2. To be an IT Supplier you need all three things at once: digital goods or services to the NHS, 50 or more staff, and £10 million or more in turnover. Picking “IT Supplier” because you sell NHS-facing software, without hitting the size thresholds, lands you in a heavier evidence set and a mandatory audit you may not need. Check the category before you check anything else. Key Structural Differences Between ISO 27001 and DSPT Four differences matter when you’re trying to reuse evidence. What they’re about. ISO 27001 is an information security standard. The DSPT is an information governance standard that includes security. A good chunk of it deals with lawful basis, transparency, data subject rights, records management, and the SIRO and Caldicott Guardian roles. None of that is in Annex A. How you’re assured. ISO 27001 gets certified once and surveilled once a year by an accredited body. The DSPT starts from a blank submission every year, and Category 1 and 2 organizations get independently assessed every year too. How granular they are. Annex A controls read as objectives (“access rights shall be provisioned, reviewed, modified and removed”). DSPT evidence items read as things to upload (“a list of all systems that hold personal data, with the date of last review”). So the mapping runs many-to-one in both directions. Where they’re heading. Since 2024/25 NHS England has been moving the Toolkit onto the NCSC Cyber Assessment Framework (CAF). CAF is outcome-based: assessors score you Achieved, Partially Achieved, or Not Achieved against an NHS England profile, rather than accepting a policy upload as proof. Category 1 organizations are already there. Category 2 and 3 are still on assertions and evidence, but NHS England has said CAF alignment will reach more organization types over time. The Business Case for Reusing ISO 27001 Evidence in DSPT How Much of DSPT Can Realistically Be Satisfied by ISO 27001 Controls For a Category 2 or 3 vendor with a full-scope ISO 27001 certificate, expect 60 to 75 percent of the mandatory evidence items to come from ISMS artifacts, either automatically (where the Toolkit auto-completes them) or with some light reframing. The rest is NHS-specific governance and information governance content that ISO 27001 doesn’t touch. The NHS’s own guidance treats reuse as a scope question. The DSPT help pages say an ISO 27001 certification must cover all health and care data processing to receive the full exemption, and that a certificate scoped only to an IT department is good evidence for many of the IT questions but not all of them. If your certificate says “the SaaS platform hosted in AWS eu-west-2” and NHS data also passes through your support desk tooling, your analytics sandbox, and a contractor’s laptop, the auto-completion won’t apply. Your assessor will want to know how those flows are controlled. Time and Cost Savings for Health-Tech Vendors There’s no fee to submit the DSPT. The cost is internal time, plus, if you’re Category 2, the independent audit and the annual penetration test the mandatory assertions expect. Building a first DSPT submission from nothing usually takes

ISO/IEC 27001 certificates nearly doubled in a single year, from 48,671 in 2023 to 96,709 in 2024, according to ISO’s own certification survey. A big share of that jump comes from startups, not enterprises. The reason is simple: buyers stopped taking “we take security seriously” at face value, and a certificate is the fastest way to prove it.  This guide covers when a startup should pursue ISO 27001, what it costs, how long it takes, and how a small team gets certified without a dedicated security department. What Is ISO 27001 and Why It Matters for Startups ISO/IEC 27001 is the international standard for information security management. It doesn’t hand you a checklist of firewalls to buy. Instead, it asks you to build and run an Information Security Management System (ISMS): a documented, repeatable way of finding your security risks and doing something about them. Certification means an accredited third party checked that your ISMS works and matches the standard. For a startup, that distinction matters. You’re not being graded on whether you own expensive tools. You’re being graded on whether you can show a system, which is exactly what an enterprise buyer’s procurement team wants to see before they sign. The Core Principles: Confidentiality, Integrity, and Availability Everything in ISO 27001 traces back to the CIA triad: confidentiality, integrity, and availability. Confidentiality means only the right people see the data. Integrity means the data is accurate and hasn’t been tampered with. Availability means the data is there when someone needs it. Every control you put in place, and every risk you assess, ties back to protecting one of those three properties. ISO puts it plainly: an ISMS that meets the standard preserves the confidentiality, integrity, and availability of information by running a risk management process. Keep the triad in mind, and the rest of the framework stops feeling abstract. How ISO 27001 Differs from Other Security Frameworks for Early-Stage Companies SOC 2 is the framework startups usually bump into first, especially when selling into the US. It results in an attestation report from a CPA firm, scoped to specific systems. ISO 27001 is a certification, recognized in over 150 countries, and it covers your whole organization through a formal ISMS with management reviews and company-wide risk assessment. The two overlap heavily. Roughly 70 to 80 percent of the controls line up, so if you do one, the second gets much cheaper. The real difference is structure. SOC 2 checks whether specific controls work. ISO 27001 checks whether you’ve built a management system that keeps those controls working over time. It also aligns closely with GDPR, which is why it travels well in Europe. Insider Note: Auditors can usually tell within an hour whether your ISMS is real or was assembled the week before the audit. A management review meeting with actual notes, decisions, and follow-ups from three months ago is worth more than a perfect-looking policy binder with no evidence anyone ever used it. When Should a Startup Pursue ISO 27001 Certification? The honest answer: when a deal, a market, or an investor is asking for it, or is about to. Certifying purely because it feels responsible is a good way to burn cash and calendar time you don’t have yet. Early-Stage vs. Growth-Stage: Timing the Certification At pre-seed and seed, ISO 27001 is usually early unless you’re selling into regulated industries or the EU from day one. Your product and processes are still shifting, and certifying a moving target means re-documenting everything a quarter later. At Series A and beyond, the math changes. Deals get bigger, buyers get more careful, and investor due diligence starts probing your security posture. Certifying while you’re 15 to 40 people is often the sweet spot: mature enough to have stable processes, small enough that scoping the ISMS is still manageable. When ISO 27001 Might Be Overkill for Your Startup If your customers are US SMBs who only ever ask for SOC 2, leading with ISO 27001 may be solving a problem you don’t have. If you’re pre-revenue and still hunting for product-market fit, your time is better spent shipping. And if no one in your sales pipeline has ever mentioned a certificate, that silence is data. Pro Tip: Pull your Last 20 Security Questionnaires Before you commit, pull your last 20 security questionnaires or RFPs and count how many explicitly asked for ISO 27001 versus SOC 2 versus nothing. That single tally answers the “which framework, and when” question faster than any consultant’s discovery call. Key Benefits of ISO 27001 for Startups Unlocking Enterprise Sales and Bigger Deals The clearest return is revenue you couldn’t touch before. Large buyers often won’t even start a security review without a recognized certificate on file. ISO 27001 gets you past the first gate of enterprise sales, and it shortens the review itself because a big chunk of the questionnaire is already answered by your certification. Building Investor and Board Confidence Certification signals operational maturity. When an investor sees a functioning ISMS, they see a founder who can build systems, not only ship features. That plays well in investor due diligence, where a security gap can stall a term sheet, and it gives your board something concrete to point to on risk. Establishing Customer Trust from Day One A certificate is third-party proof, and third-party proof beats self-assurance every time. For a young company with no brand equity yet, it’s a shortcut to being taken seriously by customers who’ve never heard of you. Creating a Scalable Security Foundation Because ISO 27001 makes you build a system rather than a one-off fix, it scales as you grow. New hires, new products, and new data types slot into an ISMS you already run. You’re not rebuilding security from scratch at every stage. Reducing Long-Term Compliance Costs Adding SOC 2, HIPAA, or ISO 42001 later is far cheaper once an ISMS exists, thanks to that 70 to 80 percent control overlap. The first framework is the expensive one.
