It’s December, and while everyone is gearing up for the grand festivities, cybercrooks are also busy developing and executing threat campaigns. There’s something about holidays and the shopping season that these threat actors love way too much. One, people really let their guards down as they try to enjoy life. Secondly, brands try to make…
When managing a domain, one of the choices you’ll face is how to configure your DNS (Domain Name System) records. Two of the most important and commonly confused record types are A records and Alias records. Though they may seem similar, they behave differently — and choosing the right one can make a big difference…
DMARC, or Domain-based Message Authentication, Reporting, and Conformance, is one of the most crucial security protocols in your email authentication setup. As it builds on SPF and DKIM, it checks whether an email is genuinely aligned with the domain it claims to come from and, if not, how it should be handled. This sounds simple,…
The best tools for bulk DMARC lookup across hundreds of domains are a mix of commercial SaaS platforms (e.g., DMARC Report, dmarcian, EasyDMARC, PowerDMARC, Valimail Monitor, MXToolbox, WhoisXML API) and high-performance open-source utilities (e.g., massdns, ZDNS, ProjectDiscovery dnsx) combined with scripting libraries (Python dnspython, Go miekg/dns) for automation and validation at scale. Bulk DMARC lookup…
As cyber threats escalate in frequency and sophistication, companies can no longer treat security as an afterthought. A robust cybersecurity posture demands proactive measures, and one of the most powerful among them is penetration testing. In this article, DMARCReport walks you through how penetration testing can significantly bolster your defenses — as well as the…
Compared to MXToolbox, Valimail, and DMARCian, DMARC Analyzer provides stronger guided onboarding and automated validation than MXToolbox and DMARCian but less end-to-end automation than Valimail; in practice, organizations tend to reach p=reject fastest with Valimail or DMARC Report, steadily with DMARC Analyzer, slower with DMARCian, and slowest with MXToolbox. DMARC setup is notoriously cross-functional—touching DNS,…
In our recent webinar titled “From Setup to Success: Secure Your Emails with DMARCReport,” we explored essential aspects of email security, with a deep dive into authentication protocols and best practices. The session was rich in content and attracted many participants; yet, we couldn’t cover all questions during the live Q&A. In this post, DMARCReport…
The best DMARC checker depends on your goals: choose dmarcian for deep DMARC-specific analytics and guided rollout, MXToolbox for fast diagnostics and budget-friendly monitoring, Proofpoint for enterprise-scale enforcement with threat intelligence, and consider DMARC Report to bridge gaps with scalable parsing, automation, and cost efficiency across SMB to multi-domain enterprises. DMARC (Domain-based Message Authentication, Reporting…
Email spoofing remains one of the common tricks used to impersonate trusted senders, targeting iCloud users. In a situation where custom domains connected to Apple Mail remain unauthenticated, an attacker can send a fraudulent message that appears legitimate at the same time as a user’s authenticated session. This poses a risk of data exposure, combined…
If you’ve ever managed a domain or hosted a website, you’ve likely encountered DNS records — but not all DNS records are created equal. Two of the most foundational types are the A record and the AAAA record. On the surface, both serve the same essential purpose: they map a domain name (like example.com) to…
