Let’s be honest, outsourcing development is a massive part of modern business. Whether you are a startup needing an MVP or an enterprise scaling up operations, handing over coding to an external team saves time and money. But it also introduces a significant risk: loss of control. That is exactly where ISO 27001:2022 Annex A 8.30 comes into play.
This control is all about ensuring that just because you have outsourced the work, you haven’t outsourced the responsibility for security. If you are looking to get certified or just want to tighten up your ship, understanding this control is non-negotiable.

What is ISO 27001 Annex A 8.30?
In simple terms, Annex A 8.30 requires an organisation to direct, monitor, and review activities related to outsourced system development. It replaces the old Annex A 14.2.7 from the 2013 version of the standard.
The goal is straightforward: you need to make sure that the external agency, freelancer, or software house follows the same rigorous security standards you would apply internally. You can’t just sign a contract and hope for the best. You need assurance that your data, intellectual property, and code are secure throughout the entire lifecycle.
Why is this Control Important?
When you outsource, you are effectively opening a door to your infrastructure. If your vendor doesn’t practice secure coding, or if they handle your data on insecure devices, your organisation suffers the consequences. Implementing this control helps you:
- Protect sensitive data and Intellectual Property (IP).
- Ensure compliance with legal and regulatory requirements (like GDPR).
- Minimise the risk of supply chain attacks.
- Maintain the integrity of your software supply chain.
For a broader look at how this fits into the standard, resources like ISO27001.com can be quite helpful for navigating the full list of controls.
Key Components of Implementation
Implementing Annex A 8.30 isn’t just about sending a questionnaire once a year. It involves a continuous cycle of definition, monitoring, and review. Here is how you can break it down.
1. Due Diligence and Vendor Selection
Before you even sign on the dotted line, you need to know who you are dealing with. This ties in closely with Annex A 5.19 (Information Security in Supplier Relationships). You should conduct a risk assessment to understand the potential impact of outsourcing this specific development work.
Ask yourself:
- Does the vendor have their own security certifications (like ISO 27001 or SOC 2)?
- What is their track record regarding data breaches?
- Do they have robust HR security practices (background checks) for their developers?
2. The Contractual Agreement
Your contract is your strongest weapon. It needs to be explicit about security requirements. Vague phrases like “we will be secure” won’t cut it. You need to specify exactly what you expect.
Consider including these elements in your agreements:
- Secure Design and Coding: Mandate that they follow secure coding principles (like avoiding the OWASP Top 10 vulnerabilities).
- Testing and Evidence: Require them to provide evidence of testing. This includes scanning for malware and conducting vulnerability assessments before delivery.
- Right to Audit: Ensure you have the right to audit their processes or review their third-party audit reports.
- Escrow Agreements: If the vendor goes bust, you need to ensure you can still access your source code.
- Intellectual Property (IP): Clearly define who owns the code and the IP rights to prevent disputes later.
3. Secure Development Lifecycle (SDLC)
You cannot effectively manage outsourced development if you don’t have a standard for it. You should establish a Secure Development Lifecycle that the vendor must adhere to. This includes threat modeling at the design phase and rigorous acceptance testing before the code goes live.
You should also ensure that the development environment is secure. Just because it’s a “dev” environment doesn’t mean it should be wide open. Access controls and data protection measures are just as vital here.
4. Monitoring and Review
This is the “continuous” part. You need to regularly review the vendor’s performance. Are they hitting their security KPIs? Have there been any incidents? Regular meetings and reports are essential to ensure they aren’t drifting away from the agreed standards.
Practical Considerations for Auditors
If you are preparing for an audit, the auditor is going to look for evidence that you are actually managing these relationships. They might ask to see:
- The contracts containing specific security clauses.
- Evidence of your due diligence or vendor risk assessments.
- Reports or logs showing that you have reviewed the vendor’s testing results (e.g., penetration test reports).
- Acceptance testing records showing you verified the security of the deliverable before deploying it.
Common Challenges
One of the biggest hurdles is the “black box” problem, where you have no visibility into the vendor’s daily operations. To counter this, establish clear communication channels and demand transparency. Another challenge is resistance from vendors regarding strict security clauses. The key here is to present security as a mutual benefit—protecting their reputation as much as yours.
Conclusion
ISO 27001 Annex A 8.30 is about extending your security perimeter to include your partners. By setting clear expectations, writing strong contracts, and keeping a watchful eye on the development process, you can enjoy the benefits of outsourcing without losing sleep over security risks. It’s not just about ticking a box; it’s about building a secure ecosystem for your software.
