Reasonable Cybersecurity for Small Professional Services Firms
A practical guide to implementing reasonable cybersecurity controls without overcomplicating things.
If you own a small accounting, law, or professional services firm, you may be wondering what "reasonable cybersecurity" actually means for your business. Like many business owners, your first question is likely:
What do we actually need to do?
The answer is simpler than you might think. You don't need enterprise-grade security teams or expensive custom tooling. You need practical, foundational controls that reduce real risk.
This article explains what reasonable cybersecurity looks like for a small professional services firm, how to approach it without overcomplicating things, and how to build a program that makes sense for your firm's size and resources.
What is "reasonable cybersecurity"?
Reasonable cybersecurity controls are about implementing safeguards that fit your business size, the data you handle, and the threats you face. It's not about perfection; it's about being intentional and practical.
Many regulations and frameworks point toward recognized cybersecurity standards, such as:
- CIS Critical Security Controls
- NIST Cybersecurity Framework
For most small and midsize firms, this means showing you have taken clear, defensible steps to reduce cybersecurity risk. You don't need to implement every control in every framework. You just need to demonstrate that you're taking responsible steps that align with industry best practices.
This concept commonly appears in regulations and insurance requirements, including Texas SB 2610.
Why small firms need to take cybersecurity seriously
Cybersecurity is not just a concern for large enterprises.
Professional services firms often handle:
- Client financial data
- Legal records
- Tax documents
- Personally identifiable information
Small firms are frequently targeted because they hold valuable data but often have fewer security controls in place. Attackers know that smaller organizations may be easier targets, making them attractive for data theft, ransomware, and other attacks.
Beyond the direct threat, many clients and regulators now expect firms to demonstrate they take cybersecurity seriously. Having a reasonable cybersecurity program in place helps you meet these expectations and protect your business.
What reasonable cybersecurity does not require
This is where many firms get unnecessarily overwhelmed.
Reasonable cybersecurity does not require perfection.
You do not need to implement every control in every framework or operate like a large enterprise. What matters is showing that you are taking responsible, appropriate steps for your business size and the data you handle.
A practical framework to follow
For small professional services firms, the most practical baseline is CIS Controls v8 Implementation Group 1 (CIS IG1).
CIS IG1 focuses on foundational controls such as:
- Knowing what devices and users exist in your environment
- Securing endpoints with modern protection
- Using strong identity and access controls
- Backing up critical data
- Applying basic network security practices
- Training users on security awareness
These controls are practical for small teams and provide a solid foundation for reasonable cybersecurity. Taking these steps reduces your risk of costly downtime or data loss. You don't need a big IT department to get these basics right.
What "reasonable cybersecurity" looks like in practice
In real terms, a reasonable cybersecurity program usually includes:
- Managed and encrypted endpoints
- Multi-factor authentication for email and critical systems
- Centralized patching and updates
- Modern endpoint detection and response
- Secure backups that are tested
- Basic logging and monitoring
- Documented policies and procedures
- A clear incident response plan
You don't need everything on day one. What matters is having a plan and making steady progress. Start with the highest-risk areas and build from there.
A simple self-check for business owners
If you want to quickly sanity check where your firm stands today, ask yourself the following questions:
- Do all users have multi-factor authentication enabled for email and critical systems?
- Are all company-owned laptops and desktops encrypted and centrally managed?
- Do we know exactly where client data is stored and who has access to it?
- Are backups not only running, but also periodically tested for recovery?
- Do we consistently apply operating system and software updates?
- Do we have a written incident response plan, even a basic one?
- Could we explain our security approach to a client or regulator if asked?
If you answered "no" or "I am not sure" to more than a few of these, it doesn't mean you're failing. It simply means your security program has grown organically and now needs some structure. Every successful business owner faces this at some point.
Why documentation matters
One of the most overlooked aspects of reasonable cybersecurity is documentation.
It is not enough to say "we are secure." You should be able to show:
- What controls do you have in place
- How they are managed
- Who is responsible for them
- How you respond to incidents
Good documentation turns security from a vague concept into something you can stand behind, with clients, regulators, and your own team. It also protects your business during staff transitions or audits, and helps ensure consistency and continuity as your team grows or changes.
