In 2024, Guardio’s email protection systems identified unusual patterns in email metadata, related explicitly to SMTP servers and their authentication as legitimate senders.

No matter how vulnerable email communications get, this mode is here to stay for the coming years. Cybercriminals are very clear about the fact that emails are the backbone of businesses, and that’s exactly why they keep targeting them. With the advent of artificial intelligence, it has become easier for them to send spoofing and phishing emails on behalf of reputable firms, impersonating their employees and CXOs. They are always ahead of the curve and keep devising new strategies and social engineering tactics to manipulate email recipients while evading detection.
In a world where emails are a crucial aspect of communication, making sure your messages get to the right people is more important than ever. Imagine sending a key email to a colleague only for it to get lost in the sea of spam—frustrating, right? That’s where SPF records come into play. They act as a security badge for your emails, showing that they are coming from a trusted source. Creating and managing these records can seem complicated, but with the right tools and guidance, you can easily enhance your email security. Dive in with us as we explore how an SPF record generator can be your best ally in keeping your communications safe and sound.
Running a subscription business is a worthwhile venture, but it equally comes with risks—especially when it comes to cybersecurity. Think payment fraud, account takeovers, and data breaches.

As of 2025, cybercrimes have become a global issue. A report says there are over 17 billion hacking attempts every day and about 5.5 billion malware attacks each year.. And this is exactly why the cyber insurance market size is estimated to be valued at $19.35 billion in 2025 and is expected to reach $71.44 billion by 2032. This exhibits a compound annual growth rate or CAGR of 20.5% from 2025 to 2032. (more…)
Email was never actually built with keeping security in mind. Back in the day, it was just a medium of communication, and it operated on trust. This made it a vulnerable target for threat actors who started exploiting email for spoofing, phishing, and spam. Over the years, email threats evolved, triggering the need for authentication mechanisms to verify if the sender is actually who they are claiming to be and protect recipients.
In the ever-connected age of digital communication, your email strategy can make or break your business’s success. Have you ever wondered why some emails seem to disappear into the void while others land right where they’re supposed to? This is where an SMTP relay server comes in. Think of it as a magical postman, ensuring your important messages fly through cyberspace and reach their intended inboxes unscathed.
In the digital age, sending emails that land straight in your recipient’s inbox instead of the dreaded spam folder is crucial for any business or individual wanting to connect. But how do you ensure that your email is recognized as legitimate and not a clever guise for phishing attempts? This is where understanding SPF—Sender Policy Framework—steps in as your email’s best ally. It’s not just a technical jargon; it’s a fundamental element in your email strategy that can make or break your communication efforts.
