Most founders spend their first few weeks on business registration, branding, and getting a website up. Security doesn’t cross their minds until something breaks. But one compromised email or leaked customer file can undo months of progress. The five things covered here don’t need technical know-how and you can knock them all out in a single afternoon.
Start With Passwords (And Actually Use a Manager)
You’ve heard it before: don’t reuse passwords. But when you’re creating a dozen accounts in your first week, it’s easy to fall back on the same one you’ve had since uni.
A password manager fixes this. Tools like Bitwarden or 1Password will generate long, random passwords for every account and keep them behind one master passphrase. Set it up on day one and add each new account as you go. That one habit alone will block the most common way attackers get in.
Turn On Two-Factor Authentication Everywhere
Passwords on their own aren’t enough. Two-factor authentication (2FA) adds a second check at login, typically a short code from an app on your phone. So even if someone gets your password, they still can’t access your account without that code.
Start with your email, then your bank, payment processor, and anywhere you store customer data. The Cybersecurity and Infrastructure Security Agency (CISA) lists multi-factor authentication as one of the top actions a small business can take. Most services support it now, and it’ll take about two minutes per account to switch on.
Lock Down Your Email
Your business email is the key to pretty much everything else. Password resets, invoices, contracts, customer conversations. If someone gets into your inbox, they can reset passwords on your other accounts, intercept payments, or pretend to be you when emailing clients.
On top of 2FA (which you should already have turned on by now), be careful with links and attachments, even from people you know. Set up email filtering if your provider offers it. And if you’re still running things through a free personal email address, consider switching to a provider with custom domains and better spam protection. You’ll look more professional and have better control over security.
Choose the Right Place to Store Your Files
This is where a lot of new founders trip up. They’ll save contracts, financial records, and customer details in whatever cloud folder came with their email, without thinking about how that data is actually protected. Most consumer cloud storage providers can technically access your files because they hold the encryption keys. That’s fine for photos, but not when you’re storing business documents.
End-to-end encrypted online storage keeps your files locked so only you can decrypt them. The provider can’t read what you’ve uploaded. Several privacy-focused providers offer free tiers with enough space for the early months.
Encrypt Your Devices
If your laptop gets nicked from a coffee shop or your phone falls out of your pocket on the bus, encryption is what stops someone from reading your files. Without it, anyone with physical access to your device can pull data straight off the hard drive.
Windows has BitLocker and Mac has FileVault, both built in and both can be turned on in your settings in under five minutes. Do the same for your phone. Modern iPhones and Android devices encrypt by default when you set a passcode, but double-check that it’s active. It costs nothing and could save you if things go wrong.
What Comes After the Basics
These five steps won’t make your business bulletproof, but they’ll put you ahead of most early-stage founders. The FBI’s Internet Crime Complaint Center reported over $16 billion in total cybercrime losses in 2024, with small businesses disproportionately targeted because attackers know their defences tend to be weaker.
Once you’ve covered passwords, 2FA, email security, device encryption, and secure file storage, you’ll have a solid baseline to build on as your business grows. Block out a couple of hours this week and get it done.
