July marks the perfect time for small businesses to conduct a comprehensive security review. With the first half of 2025 behind us, you've likely accumulated new software, updated processes, and possibly added team members. A mid-year security audit helps identify vulnerabilities before they become problems and ensures your business stays protected as you head into the second half of the year.
Why Mid-Year Security Reviews Matter
The middle of the year provides a natural checkpoint for security assessments. Your business has likely evolved with new tools, processes, and potential security gaps since January. Summer months also present unique challenges, as vacation schedules can leave systems less monitored and cybercriminals often increase activity during these periods.
Key Statistic: Recent research shows that 43% of cyberattacks target small businesses, yet only 14% of these companies consider themselves prepared to handle such incidents. A systematic approach to security can prevent most incidents before they impact your operations.
Your 7-Step Mid-Year Security Audit Checklist
1. Quarterly Security Review Framework
Establish Your Baseline
Start by documenting your current security posture. Create a simple spreadsheet listing all your business's devices, software, and access points. This inventory becomes your security roadmap for the rest of the year.
Key Actions:
- List all computers, mobile devices, and IoT equipment
- Document all software subscriptions and licenses
- Map out who has access to what systems
- Review any security incidents from the first half of 2025
- Set security review dates for October and December
Time Investment: 2-3 hours initially, then 30 minutes quarterly
2. Password Hygiene Mid-Year Cleanup
Password security remains one of the most effective defenses against unauthorized access. A mid-year cleanup helps identify weak passwords that may have been overlooked during day-to-day operations.
Password Audit Steps:
- Run a password strength assessment using business password management tools
- Identify accounts still using passwords from 2024 or earlier
- Update default passwords on any new equipment purchased this year
- Review shared account passwords and implement unique credentials
- Enable two-factor authentication on all critical business accounts
Two-factor authentication adds a crucial security layer beyond passwords. Learn more about implementing this essential security measure in our guide to two-factor authentication for online account security.
Common Weak Passwords to Replace:
- Seasonal passwords like “Summer2025” or “July2025”
- Sequential passwords like “Password123”
- Company name variations
- Default equipment passwords
Recommended Tools
| Tool | Price | Best For |
|---|---|---|
| 1Password Business | $7.99/user/month | Small teams wanting advanced features like Travel Mode |
| Bitwarden Business | $5/user/month | Budget-conscious businesses want transparency |
| LastPass Business | $6/user/month | Teams prioritizing ease of use |

- Mobile device operating systems
- General Updates (Schedule for a convenient time)
- Feature updates for productivity software
- Non-security firmware updates
When updating business productivity suites like Microsoft 365, ensure you get the latest security features and compliance tools to protect your business data.
Audit Process:
- Check Windows Update status on all computers
- Review Mac Software Update on Apple devices
- Verify that automatic updates are enabled where appropriate
- Update router and network equipment firmware
- Review mobile device management policies
Pro tip: Create a simple tracking sheet with device names, last update date, and next scheduled maintenance window. For comprehensive network protection strategies, see our complete guide to small business network security.
4. Employee Security Training Refresher
A 2025 study by Mimecast found that 95% of data breaches involved human error, with just 8% of staff accounting for 80% of security incidents. A mid-year security training session helps reinforce good practices and addresses new threats that have emerged.
July 2025 Training Focus Areas:
- AI-Enhanced Phishing: New sophisticated email scams using AI-generated content
- Social Media Security: Protecting business information on personal profiles
- Remote Work Best Practices: Securing home office environments
- Mobile Device Security: App permissions and public Wi-Fi safety
Training Delivery Options:
- 30-minute team meeting covering key topics
- Online training modules (KnowBe4, Proofpoint offer excellent programs)
- Email security reminders with practical examples
- A simple security reference card for each employee
Key Metrics to Track:
- Number of employees who completed training
- Phishing simulation test results
- Security incident reports before and after training
5. Backup System Validation
Regular backups protect against ransomware, hardware failure, and human error. However, backups are only valuable if they actually work when needed.
Backup Testing Protocol:
- Verify Backup Completion
- Check that all scheduled backups completed successfully
- Review backup logs for any error messages
- Confirm all critical data is included in backup sets
- Test Data Recovery
- Perform a test restore of a non-critical file
- Time the recovery process
- Verify file integrity after restoration
- Review Backup Storage
- Confirm that off-site backups are functioning
- Check the cloud storage account status and capacity
- Test access to backup systems from different locations
Backup Strategy Recommendations:
- 3-2-1 Rule: 3 copies of data, 2 different media types, 1 off-site
- Cloud Solutions: Carbonite, Backblaze, or Acronis for automated protection
- Local Backups: Network attached storage (NAS) for quick recovery
- Testing Schedule: Monthly quick tests, quarterly full restoration tests
