At SH Consulting, our mission goes beyond protecting individual clients - we work to strengthen the entire email ecosystem. Our security research team operates continuously to uncover critical vulnerabilities in mail servers, DNS infrastructure, and authentication protocols that are frequently exploited by threat actors.
We investigate how these weaknesses are being abused, assess the potential impact, and assist organizations - from startups to global enterprises - in closing the gaps before they are used against them.
While our primary focus is on technology companies, we also conduct in-depth research and vulnerability audits across:
Sadly, these industry and public sector organizations are frequent targets for spoofing, phishing, domain abuse, and infrastructure-level attacks due to high data value, prominence in local geographies, or limited email defense maturity.
SH Consulting is a responsible actor and trusted participant in the email security community. In most cases, we mitigate the discovered issue before reporting it, ensuring it is not exploited in the wild.
Email authentication protocols (SPF, DKIM, DMARC)
DNS misconfigurations (e.g., CNAME dangling, missing CAA records)
TLS/SSL issues, including downgrade vulnerabilities and misissuance
Email server misconfiguration & open relays
Website attack surfaces related to email intake or user data forms
These findings underscore the urgency of closing configuration gaps across industries.
SH Consulting works closely with major email security vendors and DNS service providers to enforce emerging security standards, support coordinated disclosures, and advocate for a safer digital communication environment.
Make email more secure for everyone.
We continuously track updates in protocol specifications, such as DMARC extensions, MTA-STS best practices, and DNSSEC deployment models, aligning our tools and guidance with evolving global standards.
