Handling patient data comes with serious responsibility. Under HIPAA, any information that can identify a patient must be protected at all times. This includes details like names, medical history, prescriptions, and insurance records. For businesses in healthcare and related industries, keeping this data secure is not optional. It is a basic requirement. Email, however, is…
Work looks different now, doesn’t it? Employees are the reason. Recent research from Gallup shows that six in ten employees prefer a hybrid work arrangement. No wonder the offices are now spread out, and so is the control IT once had. That makes it much harder to keep everyone secure. This shift has amplified a…
It is easy to think that once an email leaves your server, it will reach the recipient safely, exactly how it was sent. This usually does not happen because cyberattackers have developed ways to intercept your outgoing emails, modify their content, or impersonate your domain before it reaches the recipient. Since your outgoing email passes…
To set up a DMARC policy for Gmail/Google Workspace domains, configure SPF (v=spf1 include:_spf.google.com -all), enable and publish a 2048-bit DKIM key from the Google Admin console (selector._domainkey), then add a DMARC record at _dmarc.yourdomain.com starting with v=DMARC1; p=none; rua=mailto:reports@yourdomain.com; ruf=mailto:forensics@yourdomain.com; fo=1; adkim=s; aspf=s; pct=100 (optionally sp=quarantine/reject), monitor for 2–4 weeks with DMARCReport, escalate to…
DMARC lookups help you prove compliance with email security policies by producing verifiable, timestamped evidence of your enforced DMARC configuration (e.g., v, p, rua, ruf, pct, adkim, aspf, sp), which—when stored, correlated with DMARC reports and SPF/DKIM/log data, and demonstrated over time—forms an auditable chain that shows your policies are configured correctly, active across all…
Phishing is no longer just a nuisance—it has evolved into one of the most persistent and damaging cybersecurity threats facing organizations today. At DMARCReport, we continuously analyze global email traffic, authentication patterns, and attack vectors to understand how phishing is evolving and what organizations must do to stay protected. What the data shows is clear:…
Receivers most often fail to recognize a DMARC DNS record because of syntax or tag-value errors (for example, missing v=DMARC1 or invalid p=), wrong DNS type or placement (DMARC must be a TXT at _dmarc.yourdomain), provider UI formatting or TXT-length mishandling, propagation/TTL and negative caching, DNSSEC or delegation problems, invalid or unverified rua/ruf URIs, duplicate/conflicting…
Last week was all about the big names that got targeted by threat actors. The attacks look a bit more sophisticated. For instance, cybercrooks have been abusing Google Account security pages to gain access to sensitive data, such as passcodes. Qatar Airways suggests that agents use verified platforms. Australia-based LinkedIn accounts are being easily targeted…
A DMARC generator helps you discover and fix SPF issues (excessive DNS lookups, bad include chains, missing ip4/ip6 ranges, syntax errors), DKIM problems (missing/invalid signatures, wrong selector, weak keys, canonicalization mismatches, domain misalignment), DMARC record mistakes (multiple records, malformed tags, wrong p/pct, incorrect or unauthorized rua/ruf URIs), third‑party sender alignment gaps (marketing/CRM/cloud platforms not aligned…
This is the 4th edition of the month, and here are the top 4 cyber mishaps from last week that you must know about. Uniswap Founder has raised concerns around spiked instances of phishing scams. Meanwhile, threat actors have started abusing Meta ads to carry out cyberattacks. Experts witnessed a steep spike in instances of…
You send an email expecting it to reach the recipient without any problems. Your domain authentication is set up correctly. The content looks normal. There are no clear mistakes, and everything seems fine from your side. But instead of being delivered, the email returns a hard bounce message: 550 From address violates UsernameCaseMapped policy. This…
