About Cyberpresso
Cyberpresso is a free daily cybersecurity newsletter from Dupple that covers the threats, advisories, breaches and security tools that matter each day for CISOs, security operations teams and GRC professionals. You get the stories that change your work, from primary sources, in the time it takes to finish a coffee.
What Cyberpresso does
The daily brief
Every weekday morning, Cyberpresso picks the stories that matter in cybersecurity from hundreds of sources and explains each one in a few sentences. You can read the whole issue in about five minutes and know what changed.
Reviews and guides
We publish software reviews and guides for cybersecurity teams, with prices checked against the vendor's own page. Some offers on our pages may be paid placements or contain affiliate links. Our editorial content is written independently, and a placement never changes a ranking score or the editor's take.
Sponsorships
Companies that sell to our readers can sponsor an issue. Every sponsorship is labelled, so you always know what is editorial and what is paid.
What makes Cyberpresso different
Five minutes, not fifty links
Each issue is edited down to the few stories worth your time, with a line on why each one matters. Link roundups leave that work to the reader.
Primary sources first
We cite the filing, the advisory or the company's own release. Aggregators are a second source, never the only one.
A measured audience
Subscriber counts and the 29% average open rate on this page come from our email platforms and refresh every week, rather than being typed once into a media kit.
At most three sponsors per issue
We cap each issue at three labelled sponsors, so you always know which part of an issue is paid.
One of six Dupple briefs
Cyberpresso shares its editorial standards with five sister newsletters read by 930,000+ professionals in total, so a story that crosses into another field gets the right expert.
