Troubleshooting common BIMI issues

 

You probably already know that your logo is one of the biggest assets your brand owns, but wouldn’t it be great if it showed next to your emails in the inboxes of your recipients? The way to make that happen is BIMI, which stands for Brand Indicators for Message Identification. BIMI lets your logo show up next to your emails when they land in the recipient’s mailbox, which will help your brand stand out and build trust with your audience.

Building a zero-trust security model for emails

Building a zero-trust security model for emails

 

According to Verizon’s 2023 Data Breach Investigations Report, somewhere between 75% and 91% of targeted cyberattacks start with an email. Considering that such statistics surface in the news every day, organizations are trying to keep up with the growing number of sophisticated cyberattacks. Email is one of the most exploited vectors for phishing and ransomware attacks. Traditional security measures and technologies are evidently failing to ward off new-age cyberattacks; that’s why the latest solutions, like zero-trust security models, are emerging as robust alternatives.

Basics of DKIM syntax and tags

Basics of DKIM syntax and tags

 

DKIM stands for DomainKeys Identified Mail, a cryptography-based email authentication protocol that helps receiving servers verify if an email sent from your domain was tampered with in transit. If you have DKIM deployed for your domain, then your server will affix a digital signature to the header with each outgoing email. This is a cryptographically secured signature that is produced using a private key that is known only to you. The counterpart of the private key is a public key, which is published in the DNS of your domain.

They wiped away 1.15 crores worth of life savings while posing as Central Bureau of Investigation (CBI) officers, Mumbai police, and Enforcement Directorate (ED) officers. However, due to the awareness of the relatives and the agility and expertise of authorities, five threat actors got arrested red-handed as they withdrew a part of the scammed money.

How are DMARC enforcement and DMARC reporting different?

How are DMARC enforcement and DMARC reporting different?

 

Domain-based Message Authentication, Reporting, and Conformance (DMARC) is one of the most powerful tools that security teams rely on to combat email-based attacks such as phishing, spoofing, and Business Email Compromise (BEC). Essentially, this tool enables domain owners to protect their domains from scammers by specifying how emails should be handled if they fail authentication checks. But the best part about DMARC is that it goes beyond enforcing policies to block malicious emails; it gives you insights into all that’s going on with your domain and its email traffic. We are talking about the reporting aspect of DMARC, which works hand-in-hand with enforcement to create a complete email security system.

Email deliverability is the backbone of email marketing campaigns; your effort in strategizing and executing the campaign will go to complete waste if half of your emails don’t reach the inboxes of the intended recipients. If you have deployed email authentication protocols like SPF and DKIM and ensured their TXT records aren’t amiss, receiving mail servers will consider emails sent from your domain by authorized senders as genuine and, hence, will not hesitate to place them in the inboxes.

Understanding the ins and outs of attack simulations

Understanding the ins and outs of attack simulations

 

Attack simulation is a cybersecurity technique that tests defenses by imitating tactics, methods, and procedures used by threat actors to exploit vulnerabilities and launch attacks. Its purpose is to spot system vulnerabilities and help the security team remediate them before someone capitalizes on them for malicious purposes.
