Charity data security: Practical guide for nonprofits

We're not here to scare with horror stories, but let's be frank about the worst-case scenario.

When a charity suffers a data breach, it's not just about regulatory fines (though those £3 million ICO penalties certainly sting). It's about the grandmother who stops donating because she's lost trust. It's about the vulnerable young person whose personal details are now in the hands of people it shouldn’t be. It's about your CEO explaining to the board why your reputation took a hit. 

Commercial organisations can often weather these storms through sheer financial muscle and marketing spend. Charities don't often have that luxury. Your reputation is your lifeblood, and great charity data security helps to protect it. 

Why generic policies fall short

Here's something we've learned from working with hundreds of charities: copying a commercial data security policy and slapping your logo on it just doesn't work. Nonprofit organisations have unique vulnerabilities that require tailored approaches: 

• Resource constraints:

Unlike commercial entities, you probably can't throw unlimited budget at the latest security tools. Your data security policy for nonprofits needs to be smart, not expensive.

• Varied access:

Commercial businesses deal with employees and maybe some contractors. You're managing staff, volunteers, trustees and maybe even seasonal helpers - each with different levels of access needs and security awareness.

• Emotional data:

The information you hold isn't just personally identifiable - it's often deeply personal. This data requires extra layers of protection that standard commercial approaches simply don't address.

• Mission pressure:

There's always pressure to prioritise service delivery over back-office functions like security. We get it - but this is exactly when vulnerabilities creep in.

Firstly, don’t overdo it. If your policies and processes are relentlessly long and complex, they aren’t appealing for your team to read and follow. Start with the basics, but do them properly. Here’s three other points to consider: 

Foundation security

This means robust password standards (using a password manager is great), regular software updates, and access controls that actually match people's roles. It’s always worth checking if the lovely lady managing volunteers needs the same system access as the finance director. 

Charity-specific protections

This is where generic policies usually fail. Your data security policy for nonprofits needs to account for things like: 

• Seasonal volunteer onboarding and offboarding 
• Remote access for home-based fundraisers
• Integration security between your various nonprofit tools
• Data retention policies that respect both legal requirements and beneficiary dignity

Cultural security

The best technical security in the world can be quickly deemed useless if your team don't buy into it. Building a positive “no question is silly about security” culture, where reporting concerns is rewarded, and where everyone understands they're protecting the mission, works really well.  

Writing a data security policy for nonprofits is the first part. Getting people to follow it? That's where the magic happens. Here are approaches we’ve seen work in charities: 

• Make it relevant:

Don't talk about abstract threats. Talk about Sarah, your most long-term supporter, whose personal information could end up being used to exploit her further. Make it real. Bonus points for making it fun. 

• Make it achievable:

If your charity data security relies on expensive software your charity can't afford, it's not a policy - it's a wishlist. Focus on high-impact, low-cost measures first. 

• Make it ongoing:

Your charity data security approach should evolve with your charity. Annual reviews aren't enough when the threat landscape changes monthly. Learn and improve.

The technology question 

Should your charity go for the latest, most expensive security tools? Usually not. Should you accept substandard protection because "we're just a charity"? Absolutely not. 

The sweet spot is understanding exactly what level of security your specific charity needs, then building systems that deliver that protection reliably and affordably. This is where choosing the right partners becomes crucial. Make sure you do your research. 

When evaluating any technology provider - whether it's for a charity CRM, email service or website builder - ask questions about security. For example: 

• How do they handle data at rest and in transit? 
• What certifications do they hold, and who issued them? 
• How quickly can they restore your data if something goes wrong? 
• Can they provide granular access controls that match your charity's structure? 

On point two, always check that your provider is ISO 27001 certified. The longer they’ve had (and held onto) that certification, the better. It’s not easy to get, and it’s the most highly regarded global standard for data security systems.  

Security as an advantage

Here's a thought that might surprise you: excellent charity data security can actually become a competitive advantage. When donors and beneficiaries know you take their data seriously, trust increases. When funders see your robust security practices, confidence grows. When staff feel their organisation is professional and well-protected, retention improves. 

At Donorfy, we've watched charities transform from security-anxious to security-confident, and the benefits ripple through everything they do. Better security leads to better data quality, which leads to better decision-making, which leads to better outcomes for the people you serve. 

If you're reading this thinking "ugh, we really need to sort our security out," here's what we recommend: 

• Audit honestly:

Look at what you actually do, not what you think you do or wish you did 

• Prioritise ruthlessly:

Fix the biggest risks first, even if they're not the most interesting problems 

• Plan sustainably:

Choose security measures your charity can actually maintain long-term 

• Get expertise:

Whether that's training your team, working with specialists or choosing partners who understand charity-specific needs 

The conversation around charity data security is always evolving because, ultimately, this isn't about compliance or risk management - it's about protecting the people who trust you with their most sensitive information. 

The reality is that charity data security doesn't have to be overwhelming or expensive. What matters most is taking that first step, then building on it consistently. Whether you're a small local charity just starting to think about data protection, or a larger nonprofit looking to strengthen existing measures, the key is finding an approach that fits your resources and grows with your mission. 

Remember, every charity that excels at data security today started exactly where you are now. The difference is they decided to begin.
