💰 Security, Funded #208 - Summer Siesta Season
Get cybersecurity market and intelligence insights, including key trends and industry analysis, for the week of August 18, 2025.

Security, Funded by Return on Security, is a weekly analysis of economic activity in the cybersecurity market. This week’s issue is brought to you by Redsift and Nudge Security.
Hey -
Hope you had a great weekend, or a fin de semana as they say in Spain 🇪🇸 , where this week’s opener was written.
Summer is coming to a close around the world in the next few weeks, and you can tell everyone took some time off if you’ve been following along the past few weeks. The industry is experiencing its seasonal slowdown (until after Burning Man at least), but that’s not stopping the cyber industry from making significant moves.
Let’s get this bread jamón, familia. 🐷

AI is supercharging phishing. DMARC is your best defense.
Red Sift
Attackers are using LLMs to cut phishing attack costs by over 95%. DMARC provides the first line of defense against domain spoofing, stopping attackers from sending phishing emails that appear to come from your brand.
When Bitcoin.com deployed Red Sift OnDMARC, the security team blocked malicious spoofing emails within weeks—protecting both users and non-users from targeted phishing attempts.

Wow, I’m actually surprised that banning AI outright is 1) still so popular, and 2) even effective in the slightest! This sounds more like a “best effort” control, rather than a hard denial of all AI services.
Considering how many new AI services keep popping up and how all these existing platforms now have AI inside of them in some shape or form, I don’t know how security teams keep up with the approvals or the blocking.
