Digital Safety

Email is still one of the easiest ways in.

In 2026, cybercriminals are not breaking through firewalls or cracking encryption at scale. They are sending emails that look real, sound urgent, and fool people who know better.

AI has made phishing emails more convincing, business email compromise harder to spot, and attacks cheaper to run. That means more volume, better targeting, and higher success rates.

Email security is not just an IT problem anymore. It is a shared responsibility across individuals, teams, and leadership. The practices that protect email accounts are straightforward, but they require consistent habits and real buy-in.

Here is what matters most right now.

Start with Multi-Factor Authentication

Passwords are not enough. They get stolen in data breaches, guessed through brute-force attacks, and handed over in phishing scams.

Multi-factor authentication (MFA) adds a second layer of verification that makes it significantly harder for attackers to access your accounts, even if they have your password.

What to do: Enable MFA on all email accounts, especially those tied to work, finance, or sensitive systems. Use authentication apps or hardware security keys instead of SMS-based codes when possible. SMS can be intercepted, authenticator apps cannot.

If your organization does not require MFA yet, ask why. It is one of the most effective controls available, and most platforms make it easy to enable.

Slow Down Before You Click

Phishing works because it exploits urgency, trust, and distraction.

AI-generated phishing emails are more personalized now. They reference real projects, mimic writing styles, and create convincing scenarios. A message that looks like it came from your CFO, your vendor, or your IT team might not have.

What to watch for:

• Unexpected requests for sensitive information, credentials, or payments
• Pressure to act immediately without time to verify
• Unusual sender addresses that look close but are slightly off
• Links or attachments you were not expecting

Hover over links before clicking to preview the destination URL. If something feels off, verify through a separate channel. Call the person, send a new message, or check directly with your team.

Slowing down for ten seconds can prevent a breach.

Business Email Compromise Is Getting Harder to Spot

Business email compromise (BEC) scams are not random. They are targeted, patient, and often successful.

Attackers impersonate executives, vendors, or trusted partners. They request changes to payment details, approve wire transfers, or ask for confidential information. BEC attacks rely on social engineering, not malware, which makes them harder for technical controls to catch.

One of the most effective defenses against BEC is organizational culture. Teams that feel comfortable questioning unusual requests, verifying through known channels, and pausing before acting are much harder to compromise.

What to do: Verify financial requests and payment changes through a known contact method, not by replying to the email. Encourage your team to pause and verify before acting on urgent or unusual requests, especially when money or sensitive data is involved.

If someone says “this needs to happen right now,” that is often the moment to slow down.

Encryption Protects High-Stakes Communication

Most modern email providers offer some level of encryption by default, but end-to-end encryption provides the strongest protection for sensitive communications.

Encryption makes it much harder for attackers or unauthorized parties to read the content of emails in transit or at rest.

When to use it: Consider encryption for emails containing financial data, legal documents, health information, or other confidential content. Many email platforms and third-party tools make encryption straightforward to implement.

If you are emailing something you would not want exposed in a breach, encrypt it.

Keep Everything Updated

Outdated software creates vulnerabilities that attackers actively exploit. Email clients, operating systems, and browsers all need regular security updates.

Patches close known security gaps. When you delay updates, you are leaving those gaps open.

What to do: Enable automatic updates on all devices and software used to access email. Regularly check for and apply updates to email clients, browsers, and mobile apps.

This is one of the easiest, most effective controls available. Use it.

Training Makes a Difference

Technology alone will not stop every attack. People are often the last line of defense, and awareness training makes a measurable difference.

Organizations that invest in regular security training see fewer successful phishing attacks and faster threat reporting. Training works best when it is practical, relevant, and tied to real scenarios your team might actually encounter.

What training should include: How to identify phishing attempts, what to do if a suspicious email arrives, how to report potential threats, and why email security matters for the entire organization.

Training is not a one-time checkbox. It is an ongoing practice.

Review Access and Permissions Regularly

Email accounts often have more access than they need. Shared drives, financial systems, customer data, admin privileges. If an account is compromised, that access becomes the attacker’s access.

Limiting access reduces the potential damage if an account is breached.

What to do: Review who has access to what, and apply the principle of least privilege. Remove access for former employees and contractors promptly. Audit forwarding rules and third-party app permissions to ensure nothing unexpected has been added.

This is not glamorous work, but it is critical.

Separate Accounts for Different Purposes

Mixing personal and professional email increases risk. If one account is compromised, attackers may gain access to multiple systems, contacts, and data sources.

What to consider: Use separate email accounts for work, personal communication, and any high-risk activities like online shopping or social media. This compartmentalization limits exposure and makes it easier to contain a breach.

It is a small inconvenience that pays off if something goes wrong.

Email Security Is a Workforce Issue

Email security is not just a technical problem. It is a workforce issue, a leadership issue, and a trust issue. Successful attacks can lead to financial loss, data breaches, reputational damage, and regulatory consequences.

The good news is that most email security best practices are straightforward, low-cost, and scalable. They do not require advanced technical skills, just consistent habits and shared responsibility across teams.

In 2026, the most secure organizations are the ones that treat email security as an ongoing practice, not a one-time fix.
