The cost of certifications, consultants, and software can quickly add up, leaving many wondering how they can comply with ISO 27001 on a limited budget. The good news is that building an effective ISMS doesn't have to drain your resources. With the right approach, prioritisation, and smart use of tools, even smaller companies can achieve a robust information security framework.
The key to successfully implementing an ISMS on a budget is understanding that perfection isn't required. Instead, small steps, strategic choices, and incremental improvements can lead to significant long-term benefits.
By focusing on essential elements and maximising the available resources, any organisation can make meaningful progress without needing to make a massive investment.
Start Small: Prioritise Key Controls
One of the most important things to remember is that not all ISO 27001 controls need to be implemented in their most complex form from the outset. Smaller businesses can focus on the key risks and the most relevant controls for their context.
Begin with a risk assessment to determine which controls are most important to your organisation. Controls around access management, data classification, and incident response are typically good starting points.
A risk assessment doesn’t have to be a daunting, expensive exercise. You can perform a basic assessment in-house by identifying key assets, possible threats, and vulnerabilities. Consider which areas would most impact your business if compromised—these will be your priorities. Many start-ups overlook the value of a phased approach, but it can be incredibly helpful in spreading the workload and cost over time.
Start by focusing on the basic policies and procedures that are easy to implement and give you significant value, such as defining roles and responsibilities and implementing a basic password policy.
The phased approach allows you to tackle ISO 27001 in manageable portions. Once the foundational elements are in place, you can build on them gradually, reducing the pressure on resources.
For instance, securing the most sensitive information and gradually expanding controls to other areas over time can provide a sustainable path forward.
Leverage Low-Cost Tools
You don't need expensive software to manage an ISMS effectively. Plenty of low-cost or even free tools can help you get started:
Google Workspace or Microsoft 365 can be used to manage documents and ensure version control. The key is to ensure access permissions are in place and sensitive documents are appropriately protected. You can also use tools like Google Drive's sharing settings to restrict access, ensuring only authorised team members can view or edit documents.
Trello or Asana are great project management tools that can help you track action items, manage risk assessments, and keep your ISMS on track without the need for expensive GRC software. By creating boards dedicated to information security, you can maintain visibility of tasks and progress without complicated software.
Bitwarden or LastPass are affordable solutions for managing passwords and enforcing strong password policies across your team. Strong password management is a simple but highly effective security measure significantly reducing risk.
For risk management, a simple spreadsheet can be highly effective at an early stage. You can map out assets, risks, and mitigations without the need for dedicated software. Spreadsheets can also maintain records of incidents, vulnerabilities, and control measures, allowing you to demonstrate due diligence during an audit.
Remember, these tools might not be a perfect fit forever, but they can provide an effective, budget-friendly way to start developing an ISMS. The focus should be on practicality—if a tool helps you control your ISMS, it’s doing its job.
Policies and Procedures: Keep It Simple
One of the most significant misconceptions about ISO 27001 is that your policies and procedures need to be highly complex. For a smaller business, it's better to keep these documents concise and practical.
The goal is for your team to understand and follow them.
Draft key policies such as an Information Security Policy, an Access Control Policy, and an Incident Response Plan.
There are many templates available online that can serve as a starting point, and you can adapt them to fit the specifics of your company. Just be sure the policies accurately reflect what you are doing—auditors can spot a generic policy from a mile away, and having a policy that doesn’t match your practice can lead to problems.
When drafting policies, make them relatable and relevant to your team’s day-to-day work. For example, if your staff regularly works remotely, ensure your policies include guidance on securing home networks and using VPNs.
Policies that are practical and easy to understand are far more likely to be followed.
Training on a Budget
Training is essential to an effective ISMS but doesn't have to be costly. Many online platforms like Udemy or LinkedIn Learning offer affordable courses on information security basics. You can also conduct in-house training sessions to raise awareness about phishing, social engineering, and best practices for data protection.
Sometimes, the most effective training is the kind that is repeated little and often rather than relying on a one-off intensive session.
Regular phishing simulations are another cost-effective way to build security awareness. Services like PhishMe offer affordable ways to test how well your team can identify phishing attempts. You could also create your simulations internally, sending mock phishing emails to see how staff respond and then using those results as training opportunities.
Another practical option is to set up a monthly or quarterly security awareness email that covers recent threats, good security practices, and key reminders. This ongoing reinforcement can help build a strong security culture at minimal cost.
Encourage team members to report suspicious activities and make it easy for them to do so. Building a culture of openness can enhance your organisation’s security.
Engage Your Team: Shared Responsibility
In a smaller organisation, you may not have the luxury of a dedicated security team. However, that doesn’t mean information security can’t be effectively managed. By spreading responsibilities across existing roles, you can build a culture where everyone plays a part in keeping information safe.
Assign roles such as Data Protection Officer (DPO) or ISMS Coordinator to existing team members. Make sure that these roles come with clear expectations and remain manageable given the person’s other duties.
Encouraging team involvement helps make security an ongoing, shared responsibility rather than a burden. You could start by holding regular team meetings to discuss security topics, address concerns, and review recent incidents. These sessions don’t need to be long—15 to 20 minutes is sufficient to cover key points and reinforce good practices.
Security doesn’t just come from policies or software—it comes from people making the right daily choices. Creating a culture where your team understands the importance of protecting information can be far more impactful than an expensive piece of technology.
For example, staff should be comfortable challenging unexpected requests for information, even if they seem to come from senior management. Encouraging this behaviour is crucial to protecting against social engineering attacks.
Incremental Improvement
ISO 27001 is about continual improvement.
Don’t worry if your ISMS isn’t perfect right away—the important thing is to start and then keep iterating.
Regularly review your risk assessment, policies, and the incidents you've logged. Use these insights to make small, incremental improvements. This approach helps spread the effort and cost, making it more manageable over time.
One effective way to ensure continual improvement is to establish a review calendar. Scheduling monthly or quarterly check-ins for different aspects of your ISMS helps to make progress steady and predictable.
Each review should focus on specific areas, such as reviewing access permissions, reassessing risks, or updating policies based on recent incidents. Incremental improvement is at the heart of the ISO 27001 framework, and smaller businesses can greatly benefit from consistent, small updates.
Another practical tip is to involve different team members in these reviews. Bringing in fresh perspectives can uncover overlooked issues and help make sure that policies and procedures are being followed in practice.
Engaging staff in improvement efforts also reinforces the idea that everyone has a role in maintaining security.
Conclusion
Building an ISMS on a budget requires creativity, prioritisation, and a willingness to start small and grow. By leveraging low-cost tools, engaging your team, and focusing on simple but effective policies, even smaller businesses can achieve meaningful compliance with ISO 27001 without breaking the bank.
The journey to ISO 27001 compliance is more about consistency and mindset than how much money you spend. Start where you are, use what you have, and build step by step. With determination and resourcefulness, an effective ISMS is within reach. Remember, the ultimate goal is to reduce risk and protect your information—whether you’re using cutting-edge technology or simply making the best use of a shared spreadsheet, what really matters is the intent and commitment behind your actions.
Achieving ISO 27001 certification may take time, but every small step gets you closer to your goal. Stay focused on your risks, make improvements where you can, and don't be discouraged by budget constraints. With the right approach, a robust ISMS can be built without a large financial outlay, providing your business with the security and resilience it needs to grow.
