ISO 27001 Annex A 5.4 is a governance control that mandates Management Responsibilities, requiring leadership to ensure all employees and contractors actually apply security policies in their daily work. For tech startups, this control eliminates the “Founder Mode” security exemptions and provides the Business Benefit of a defensible culture that protects executives from personal liability under new regulations.
In the startup world, the mantra is often “move fast and break things.” But when you are trying to close an enterprise deal or get your ISO 27001 certification, the new mantra has to be “move fast and secure things.” This is where ISO 27001 Annex A 5.4 Management Responsibilities comes into play.
For a tech startup, this control can feel like a culture clash. It requires management to ensure that everyone applies security policies. It sounds like corporate bureaucracy, but if implemented correctly, it’s actually the secret sauce that lets you scale without crashing. Here is how to nail Annex A 5.4 without slowing down your sprint velocity.

The Business Case: Why This Actually Matters
If management doesn’t care, nobody cares. That is the physics of corporate culture. Annex A 5.4 is the control that proves your C-Suite isn’t asleep at the wheel.
- Sales Angle: Enterprise buyers know that startups are risky. They fear the “Cowboy Founder” who overrides security to close a deal. Annex A 5.4 is your counter-argument. It provides evidence that your leadership team enforces security rules, making you a safe bet for a 5-year contract.
- Risk Angle: The “Negligence Lawsuit.” If you suffer a breach and it turns out the CEO told the dev team to turn off the firewall to improve latency, that is negligence. Annex A 5.4 mandates that management requires security to be applied. Documenting this protects the company from shareholder lawsuits.
The “No-BS” Translation: Decoding the Requirement
The Auditor’s View: “Management shall require all personnel to apply information security in accordance with the established information security policy and procedures of the organisation.”
The Startup’s View: The boss cannot be the security hole. If you write a policy saying “Use MFA,” the CEO must use MFA. If you write a policy saying “Lock your screen,” the CTO must lock their screen. Management must walk the walk.
For a DevOps engineer, this translates to:
- Enforcement: “If I push code with hardcoded credentials, my manager will actually reject the PR, not just high-five me for speed.”
- Culture: “Security tickets in Jira are treated as real work, not tech debt we ignore.”

DORA, NIS2, and AI Laws
Annex A 5.4 is where compliance gets personal.
- DORA (Fintech): Places specific responsibility on the “Management Body.” They must define and approve the ICT risk management framework. You cannot delegate this accountability to a consultant. Annex A 5.4 is the proof that they accepted this responsibility.
- NIS2: Introduces personal liability for senior management. If management fails to ensure cyber security measures are applied, they can be banned from holding director positions. Annex A 5.4 is your primary legal defence to prove you took “Management Responsibility” seriously.
- AI Act: Requires human oversight. Management must ensure that staff using AI tools (like Copilot) are applying security policies regarding data privacy. If management ignores AI usage, they fail Annex A 5.4.
Why the ISO 27001 Toolkit Trumps SaaS Platforms
SaaS platforms automate “acceptance,” not “application.” There is a difference.
| Feature | ISO 27001 Toolkit (High Table) | Online SaaS GRC Platform |
|---|---|---|
| Accountability | Documents signed by humans carry legal weight. | Clicking “I Agree” on a popup is often ignored by staff. |
| Culture | Encourages face-to-face briefings and real management. | Encourages “set and forget” automated reminders that annoy staff. |
| Cost | One-off fee. | Monthly subscription for a dashboard that doesn’t actually manage your team. |
| Ownership | You define the culture. | The vendor defines the workflow. |
Top 3 Non-conformities When Using SaaS Platforms
- The “Click-Through” Illusion: The SaaS dashboard shows 100% of staff clicked “Read” on the policy. The auditor asks a staff member, “What does the policy say about USB drives?” The staff member has no idea. Fail. Management tracked the click, not the understanding.
- The “Shadow Admin” Gap: The SaaS tool monitors general staff, but the Founders have “Super Admin” accounts that bypass the tool’s checks (e.g., MFA disabled for convenience). Management failed to apply policies to themselves.
- The “Stale Policy” Trap: The SaaS tool has default policies that management never read. The policy says “We perform quarterly reviews,” but the startup does annual reviews. Management failed to ensure policies were applied as written.
The “Founder Mode” Problem
The biggest hurdle for startups with Annex A 5.4 is usually the founders themselves. You are used to having “God Mode” access to everything—production databases, AWS root accounts, the company bank account.
To comply with this control, management must lead by example. If the CTO disables MFA because it’s “annoying,” you have failed Annex A 5.4. The auditor will look specifically for this. They want to see that the rules apply to everyone, especially those at the top. You have to walk the talk.
Step 1: Bake Security into Your Tools (Jira, Slack, GitHub)
Don’t rely on a dusty employee handbook that nobody reads. To ensure policies are “applied” (as the standard requires), bake them into the tools your team uses every day.
- Onboarding: Use your HR or IT automation tool to ensure every new hire signs the Information Security Policy before they get their laptop.
- Code Reviews: Enforce branch protection rules in GitHub or GitLab. Make “Security Review” a mandatory step in your pull request process. Management’s responsibility is to ensure these checks are never bypassed.
- Communication: Use a dedicated #security-announcements channel in Slack or Teams. Post updates there and track emojis or replies as evidence of acknowledgement.
Step 2: Define Roles Without the Bloat
In a startup of 15 people, you don’t have a dedicated Compliance Officer. That’s fine. Annex A 5.4 doesn’t require new hires; it requires defined responsibilities.
- The CTO is responsible for secure coding standards and cloud infrastructure.
- The COO (or Founder) is responsible for physical security and HR checks.
- The Lead Dev is responsible for peer reviews and dependency scanning.
The Evidence Locker: What the Auditor Needs to See
To pass the audit, you need to prove that management is active, not passive. Prepare these artifacts:
- Signed Acceptable Use Policies: Proof that staff agreed to the rules.
- Management Review Minutes: Notes from a quarterly meeting where security was discussed.
- Disciplinary Records (Redacted): If someone violated security, show that management took action (even if it was just a verbal warning).
- Slack/Email Announcements: Screenshots of the CEO reminding staff about phishing or updates.
Common Pitfalls and Auditor Traps
- The “Do as I say, not as I do” Trap: The CEO shares their password with the EA. Instant fail.
- The “Paper Shield”: Having perfect policies but zero enforcement. If the policy says “Clean Desk” and the auditor sees passwords on post-it notes, management has failed.
- The “Blame the Intern”: Management claiming they didn’t know staff weren’t following rules. It is management’s job to know.
Handling Exceptions: The Break Glass Protocol
Sometimes management needs to bypass rules to save the company (e.g., emergency production fix). You need a protocol.
- The Emergency: “We need to deploy code without peer review to fix a P0 bug.”
- The Action: CTO approves the bypass explicitly.
- The Paper Trail: Log the exception in the Incident Register.
- The Review: Retroactive peer review must happen within 24 hours.
The Process Layer: Standard Operating Procedure (SOP)
Tools: Notion (Policy), Slack (Comms), BambooHR (Sign-off).
- Annual Briefing: CEO presents the “State of Security” at the company All-Hands.
- Quarterly Check: Management reviews security metrics (incidents, training completion).
- Incident Response: If a policy is breached, management conducts a “Lessons Learned” review, not a witch hunt.
Frequently Asked Questions (FAQ)
What is ISO 27001 Annex A 5.4 for tech startups?
Annex A 5.4 requires management to ensure all personnel perform information security in accordance with the established policies. For startups, this means 100% accountability from the C-suite to drive security culture and provide the 3 core resources: people, technology, and budget. It shifts security from a technical task to a business leadership mandate.
How does management demonstrate commitment under A 5.4?
Leadership demonstrates commitment by formalising security as a business priority rather than a technical task. In practice, this results in a 15–20% increase in audit success when the CEO or CTO actively participates in the Management Review Process and approves the Information Security Policy. Management must lead by example to ensure 100% policy adoption across the team.
What are the mandatory management responsibilities in ISO 27001?
Management must ensure that information security requirements are integrated into the organisation’s processes. Specific mandatory actions to satisfy Annex A 5.4 include: Establishing the information security policy and measurable objectives. Providing 100% of the necessary resources, including budget and security tooling. Communicating the strategic importance of effective information security management. Directing and supporting staff to contribute to the effectiveness of the ISMS.
Can startup management outsource security accountability?
No, management cannot outsource accountability for information security, even if they outsource technical tasks. While a Virtual CISO (vCISO) can manage 100% of the day-to-day operations, the legal and standard-based responsibility remains with the startup’s top management to ensure compliance and risk ownership. Auditors will verify that leadership retains 100% oversight of external consultants.
How often should management review the ISMS performance?
Management must review the ISMS at planned intervals, typically at least once per year, to ensure its continuing suitability. For high-growth startups, quarterly reviews are 100% recommended to manage rapid changes in infrastructure or headcount, which can increase the threat landscape by over 30% year-on-year. These reviews must be documented in formal meeting minutes as objective audit evidence.
