7 Practical Security Actions You Can Do Today
1. Check if Your Email Was Breached
Go to Have I Been Pwned and check your business email address.
If it appears in a breach:
- change the password
- enable MFA
- check where else that password was reused
- move the account into a password manager
This is one of the fastest free security wins.
2. Use a Password Manager
If your team stores passwords in spreadsheets, browsers, messages, or notes, that is a risk.
A password manager like 1Password helps teams:
- create strong passwords
- share credentials safely
- remove access when employees leave
- identify weak or reused passwords
At minimum, every important business account should have a unique password.
3. Turn On MFA Everywhere
Multi-factor authentication should be enabled on:
- email accounts
- domain registrar
- website hosting
- payment accounts
- bank accounts
- CRM and SaaS tools
- cloud storage
- admin dashboards
If an account controls money, customer data, login access, or your website, it needs MFA.
4. Scan Suspicious Links and Files
If someone sends an unexpected attachment or suspicious URL, check it before opening.
Use VirusTotal for quick triage.
You can scan:
- URLs
- files
- domains
- IP addresses
- hashes
Important: do not upload confidential customer documents or private company files to public scanning tools. Use VirusTotal for suspicious generic files and links, not sensitive documents.
5. Keep Devices Updated
Most small businesses do not get hacked through movie-style attacks. Many are hit because old software, weak passwords, or unpatched devices were left exposed.
Update:
- Windows or macOS
- mobile devices
- browsers
- WordPress plugins
- ecommerce apps
- antivirus or EDR tools
- routers and network devices
Set automatic updates wherever possible.
6. Create a Backup Plan
A backup is only useful if it can actually be restored.
Use the 3-2-1 rule:
3 copies of important data
2 different storage types
1 copy stored offsite or in the cloud
Back up:
- website files
- customer records
- invoices
- product data
- legal documents
- financial reports
- email exports if needed
Test your backup at least once per quarter.
7. Review Public Exposure
Some tools help you understand what may be visible on the public internet.
For security teams, Shodan can help check exposed services and devices. For most small businesses, this should be used carefully and only for assets you own or are authorized to review.
If you are unsure, start with CISA Free Tools and basic guidance instead.
When Should You Upgrade to Paid Security Tools?
Free tools are great for awareness and basic checks.
But consider paid security tools if your business has:
- customer data
- payment data
- employee devices
- remote staff
- compliance requirements
- sensitive documents
- high website traffic
- repeated phishing attempts
For stronger endpoint protection, compare CrowdStrike Falcon and SentinelOne.
For larger organizations that need AI-driven threat detection across networks, cloud, email, and identity, review Darktrace or Vectra AI.
