Security insights
Tool comparisons and write-ups on web security, browser privacy and malware. These sit alongside the Scan.now guides, which remain the reference material behind every check.
What you will find here
Two kinds of writing, kept clearly apart.
- Tool comparisons. Honest side-by-side pieces on how Scan.now compares with the other scanners people use — SSL Labs, securityheaders.com, Sucuri SiteCheck, Mozilla's HTTP Observatory and active scanners. Each one names something the other tool does better, because in every case there is something.
- Explainers on subjects people search for rather than subjects our tools cover — starting with what makes hacking ethical, which is a question about permission rather than technique.
- Contributed articles on web security, browser privacy and malware, reviewed for accuracy before they are scheduled and labelled with their author.
What we will not publish
We scan other people's websites all day, including our competitors'. What those scans find stays private. Our privacy policy promises that reports about third-party sites are never indexed and are deleted after 30 days, and a comparison article is not a reason to break that promise. If a scan of ours turns up something serious on somebody else's site, it goes to them, not into a blog post.
Where the reference material lives
Not here. The checks reference explains every test we run and the guides explain the subjects behind them. Those are maintained and dated; the blog is where things that are not reference material go.
