Halon and Spamhaus in email security partnership

We are excited to announce that Halon now provides official integration with Spamhaus Technology anti-spam & threat data feeds (IP & domain blocklists). Both companies worked together to ensure that this new functionality would be simple to deploy while also scaling all the way from smaller systems to large ISP’s with millions of users and complex email flows.

How I fooled Microsofts Safe Link technology in 5 minutes

The Safe Link technology was recently launched by Microsoft through Office 365. The goal of this technology is to rewrite all URL's in email to a URL classification service, so at the time of user-clicks it's possible to reclassify a URL. This method is preferred as spammers more often replace the phishing URL's site content after a message is being scanned, hence there is a need of reclassification later. Safe link is Microsoft's "best-effort" to do so.

TES meeting on email security at Old Trafford in Manchester

Email security was the topic of discussion at another Open-Xchange sponsored TES event held last Thursday in the fantastic setting of Old Trafford Stadium, the home of Manchester United. BT, TalkTalk and Plusnet, three of the largest ISPs in the UK, had delegates in attendance along with Halon and Cloudmark. This intimate group discussed the challenges facing email security as it stands today and how they could collaborate going forward to improve the state of affairs.

How One.com reduced email costs by up to 70%

Anders Saaby, CTO, One.com explains, “Due to One.com’s high growth rate, we needed to upgrade our existing email delivery and security infrastructure to a newer solution that scaled better in terms of performance and maintenance.

One.com typically develop their own software and systems as this enables them to offer truly differentiated services with many unique features, at very competitive prices. This usually rules out many commercial products, as they cannot properly support and integrate into One.com’s sophisticated and highly customized platforms.

Why you need to demand high deliverability and security of email

Trends come and go but fashion is always in style. 20 years of emails shows that it is a consistent way of communication, despite a relatively standstill in development. While the world sings their praise for new and sexy messaging services like Slack, gets rid of stationary phones, and transfer customer communication to Facebook chat bots, the B2B world still rely steadily on email.

Why everybody should use DMARC to prevent phishing

Email is a major source of phishing and malware attacks. The Locky ransomware solely contributed to a 412% increase of malware emails in March compared to February, according to CYREN's May 2016 cyberthreat report. While I believe that awareness and training is the most universally effective counter-measure, even that is really difficult, according to this recent study. We probably need a combination of training and technological advancements. One of the latter has to do with email authenticity. Can you trust an email's sender adress? Generally no, but you can with DMARC.

What is DANE?

DANE does not only challenge the certificate authority (CA) system, but also has the potential to revolutionize email security; namely making encrypted email delivery the norm. Halon Security’s mission is to bring DANE to the world of email and to help maintain data privacy and security on a
