How to Prevent Outbound Phishing Attacks?



There are many ways to prevent phishing attacks. You can use a spam filter, or you can use email authentication. In addition, you can use a reverse proxy to block outbound phishing attacks. Outbound phishing attacks are a major problem for businesses of all sizes. They can be extremely costly, not only in terms of money lost but also in terms of damage to your brand’s reputation. And the truth is, it’s really hard to prevent them.

Methods to prevent phishing attacks

Using Spam Filters

A spam filter is just a special type of email client that you install on your computer or mobile device. It filters out messages that it knows are spam, but it also lets through messages that it thinks are legitimate emails.

Why is phishing prevention important?

We know that phishing attacks, much like DNS spoofing, are on the rise, and we want to help you prevent them.

Phishing is a form of fraud that involves tricking people into providing their personal information, such as passwords and credit card numbers, by impersonating a trusted entity. It’s a common threat because it works—people fall for phishing attacks over 100 million times every year!

If you’ve ever received an email from your bank or credit card company asking you to update your details, chances are it was a phishing attack. These emails often include links to fake websites where criminals attempt to steal your information.

That’s why it’s so important to be vigilant when receiving emails from companies you do business with. Here are some tips:

  • Don’t click on links in emails that appear to be from your bank or credit card company—you should always log in directly through the official website instead.
  • Always check who an email is from before opening it—if it doesn’t look like an email sent by your bank or credit card company, don’t open it!
  • Watch out for typos and spelling mistakes in emails sent by trusted organizations; these may indicate

Enabling Email Authentication

Email authentication is a way to verify that an email is coming from the person who claims to be sending it. You can think of it as a seal of approval or a stamp of authenticity. It’s like your bank telling you that the check you received came from them—you know it’s legitimate and likely won’t bounce.

  • Use a secure email gateway
  • Enable SPF and DKIM records
  • Enable DMARC policy to reject all mail from invalid senders and check your record using a DMARC checker
  • Monitor your outbound mail

Using Reverse Proxy

A reverse proxy works by taking all outbound requests from users and making sure they’re legit before sending them off to another server somewhere else on the internet—meaning that if someone tries to send something maliciously through your network, their request will just get blocked without ever getting anywhere near your actual servers!

Train your staff

Make sure they understand what phishing is and how it works. They should know that responding to any email asking for personal information or login credentials will put their accounts at risk of being hacked.

Monitor accounts closely

If a member of your team receives an email that looks suspicious, don’t wait until the end of the day to check on it—check on it right away! If you see something like this happening often, that’s an indication that you need more training for your staff members on how to spot these types of scams early on before they get into trouble by clicking links or giving out personal information unnecessarily online where anyone can see it.


Additionally, you can amp up your protection against attacks by deploying MTA-STS to secure emails even in transit from possible man-in-the-middle attacks, and make your emails visually identifiable in receivers’ inboxes by adding BIMI logos.

Phishing is one of the most dangerous cyber-attacks out there. It can be used to steal your information and money, or even worse, infiltrate your computer with malicious software.

Because phishing is a form of social engineering, it’s designed to deceive you. It’s been around for decades and has become more sophisticated over time. It has become more common too, with some estimates suggesting that 80% of all cyberattacks start with a phishing email. So protection is not just important, it’s imperative!
