They expertly mapped the overlapping controls between SOC 2 and ISO 27001, which saved us from duplicating work.
One keeps the business running. The other protects its information. They share the same Annex SL skeleton, touch at two Annex A controls, and increasingly arrive on a vendor’s desk in the same bank assessment. This guide puts the two standards side by side — what each proves, what is reusable across them, who asks for which, and when the right answer is an integrated build of both.

Key Takeaways
- ISO 22301 and ISO 27001 answer different questions: the BCMS proves you can keep delivering prioritised products and services through disruption, while the ISMS proves you can protect the confidentiality, integrity, and availability of information. They complement — they do not compete.
- Both follow the Annex SL high-level structure (Clauses 4–10), so context, leadership, document control, competence, internal audit, management review, and corrective action can run as one integrated management system.
- The standards reference each other at the seam: ISO 27001:2022 Annex A controls 5.29 (information security during disruption) and 5.30 (ICT readiness for business continuity) expect continuity thinking inside the ISMS — but two controls do not make a BCMS.
- Who asks decides the order: banking and financial regulators (CBUAE, SAMA, APRA CPS 230) drive ISO 22301 demand, while enterprise security questionnaires and data-protection contracts drive ISO 27001. Vendors serving regulated financial institutions increasingly need both.
- Building both together as one integrated system takes meaningfully less effort than two sequential projects — and our consultants have prepared ADIB (Abu Dhabi Islamic Bank), Mashreq Bank, and AMEX for ISO 22301 in the Middle East.
Different Questions, Not Different Answers to One
The fastest way to choose wrongly is to treat these as substitutes. A certificate that proves your data is safe says nothing about whether payments keep flowing — and vice versa.
Keeps the business running
A business continuity management system proves your organisation can keep prioritised products and services operating through cyber incidents, outages, supplier failures, and disasters. Its core artefacts: a business impact analysis with RTO/RPO/MTPD targets, a disruption risk assessment, resourced continuity strategies, activation-ready plans, and a tested exercise programme.
Protects the information
An information security management system proves you can protect the confidentiality, integrity, and availability of information. Its core artefacts: an information-security risk assessment, a Statement of Applicability selecting from the 93 Annex A controls, implemented policies and controls, and the monitoring and audit evidence that they operate.
The Comparison, Dimension by Dimension
Eight dimensions that decide scoping conversations. Note the last two rows: the certification machinery is identical, but the triggers — and the people asking — are not.
| Dimension | ISO 22301 (BCMS) | ISO 27001 (ISMS) |
|---|---|---|
| Question it answers | Can you keep delivering prioritised products and services through disruption? | Can you protect the confidentiality, integrity, and availability of information? |
| Management system | BCMS — business continuity management system | ISMS — information security management system |
| Core analysis | Business impact analysis (RTO / RPO / MTPD) plus a disruption risk assessment | Information-security risk assessment driving risk treatment |
| Controls | No control catalogue — every requirement in Clauses 4–10 applies, scoped to the BCMS, with no Statement of Applicability | Annex A catalogue of 93 controls, selected through risk treatment and declared in the Statement of Applicability |
| Headline outputs | Continuity strategies, business continuity plans, exercise reports | Statement of Applicability, security policies, implemented controls |
| Proof it works | The exercise programme — scenarios run, targets tested, actions closed | Control monitoring, internal audits, technical testing evidence |
| Structure & certification | Annex SL Clauses 4–10, Stage 1 + Stage 2 by an accredited body, and a three-year cycle | Identical — same structure, same audit model, same cycle, often the same certification body |
| Typical trigger | CBUAE, SAMA, and APRA CPS 230 continuity mandates, plus continuity clauses in enterprise contracts | Enterprise security questionnaires, data-protection contracts, customer security mandates |
The Control Overlap — A.5.29 & A.5.30
ISO 27001:2022 reaches into continuity at exactly two points — and ISO 22301 assumes the information feeding recovery is secure. Build the seam once and both auditors accept it.
A.5.29 — Information security during disruption
ISO 27001:2022 requires security to hold when business is disrupted — access control, logging, and confidentiality woven into the continuity plans themselves. An ISMS without continuity thinking fails this control, and a BCMS written without security input creates exactly the gap it probes.
A.5.30 — ICT readiness for business continuity
New in the 2022 revision: ICT must be ready to recover to meet business continuity objectives — RTOs, RPOs, failover, and tested recovery plans. It is, in effect, a one-control summary of ISO 22301’s Clause 8 expectations for technology, and the clearest bridge between the two standards.
The direction of the inference matters: holding ISO 27001 with 5.29 and 5.30 in your Statement of Applicability is a continuity seed, not continuity compliance. A bank assessor reading an SoA line will still ask for the BIA, the recovery targets, and the last exercise report — the artefacts only a BCMS produces.
Who Asks for Which — and What That Tells You
The standard you need is written in the request you received. Read the source, not the acronym.
Banks & financial regulators ask for ISO 22301
CBUAE-driven UAE banks set ISO 22301 deadlines for critical vendors, Saudi Arabia’s SAMA BCM framework is built directly on the standard, and APRA CPS 230 pushes continuity evidence onto material service providers. When the request comes from a bank’s vendor-risk team or a financial regulator’s flow-down, it is the BCMS they want — BIA, recovery targets, exercise reports.
Enterprise security reviews ask for ISO 27001
Security questionnaires, data-protection addenda, and enterprise procurement gates ask for the ISMS: the certificate, the Statement of Applicability, the policies, the penetration-test summary. ISO 27001 is the default answer to “prove you can hold our data safely” — the most common gate on SaaS and services deals worldwide.
Vendors to financial institutions increasingly need both
Run a critical operation for a bank and you hold its data too — so the same vendor assessment now carries a security section and a continuity section. Gulf banks in particular ask for an ISMS and a BCMS side by side, which is why the integrated build exists.
| If this is on your desk… | Start here |
|---|---|
| A UAE or Saudi bank has set your team a BCMS or ISO 22301 deadline | ISO 22301 first — the deadline is contractual and the assessor wants continuity evidence |
| Enterprise security questionnaires are stalling your sales pipeline | ISO 27001 first — it answers the security section of nearly every questionnaire in one line |
| An APRA-regulated customer is rewriting your contract under CPS 230 | ISO 22301 first — the new clauses are about continuity, tolerance, and exercise participation |
| You run a critical service for financial institutions and hold their data | Build both as one integrated management system — one governance layer, two certificates |
| You already hold ISO 27001 and a bank now asks for ISO 22301 | Extend, do not restart — the governance layer is reusable, and the BIA, strategies, plans, and exercises are the new work |
Building Both Together — One System, Two Certificates
Sequential builds pay the governance bill twice. The integrated path builds the Annex SL frame once and hangs both operational cores on it — meaningfully less effort, and a system that reads as one organisation rather than two binders.
One governance layer
A single scope-and-context analysis covering both information security and continuity, one leadership and policy framework, one document-control system, and one set of role assignments — written once to serve both standards.
Twin analyses, one workshop series
The information-security risk assessment and the business impact analysis draw on the same people and the same dependency knowledge — running them as a coordinated series halves the workshop burden on activity owners.
Controls and continuity solutions together
Annex A implementation and continuity strategy resourcing proceed in parallel, with controls 5.29 and 5.30 built once to satisfy both auditors — security inside the continuity plans, ICT recovery aligned to the BIA targets.
One audit-and-review engine
A combined internal audit programme covers both standards’ clauses, one management review takes both systems’ inputs, and a single corrective-action loop closes findings from exercises, incidents, and audits alike.
Coordinated certification audits
Most accredited bodies offer integrated or back-to-back audits of ISO 27001 and ISO 22301, sampling the shared governance once. TCSA schedules both against your hardest external deadline and sits beside you through each stage.
Already certified to one standard? The same logic applies in miniature — we extend the existing governance layer rather than duplicating it. See the ISO 22301 implementation roadmap for the BCMS build sequence, or the ISO 27001 guide for the ISMS side.
“The expensive mistake is not choosing the wrong standard — it is building them as strangers. Two scopes, two policy suites, two audit calendars for one organisation. Build the frame once, and the second certificate is an extension, not a second project.”

In their words.
Quotes verbatim from G2. Company names added where the client confirmed them.
Instead of simply providing generic templates or checklists, their team took the time to understand our environment and requirements.
The team’s willingness to work with us and ease of communication.
They delivered the project with speed, accuracy, and cost-effectiveness.
My only regret is that we didn’t engage them sooner in our compliance journey, which would have saved us even more time.
They were always responsive and willing to go the extra mile whenever we had questions or needed guidance.
Managing the auditor relationship on our behalf was especially valuable — it took a lot of pressure off our internal team.
Their focus on ensuring that we were genuinely audit-ready rather than simply completing documentation.
The guidance was not generic or simply based on a standard checklist — they suggested practical approaches that made sense for our business.
What I like best is the hands-on support and clear guidance throughout the SOC 1 and SOC 2 process.
