SlideBySide presents itself as a slick way to share and control slides with an audience — no account needed, just a link. That convenience is appealing, and from a technical standpoint the site is well run: modern encryption, a privacy policy, and even a support email. But here's the catch: the domain was registered in October 2026, and the person or company behind it isn't named anywhere. There's no about page, no team, no social media presence. For a SaaS tool that asks you to upload your PDFs and PowerPoints, that anonymity matters. Established collaborative tools (like Google Slides or Miro) have years of history and clear ownership. SlideBySide has neither. If you're trying it out for a casual, non-sensitive presentation, it's probably fine. But if the slides contain confidential data or you plan to rely on this for work, wait until the service has a track record you can verify. That 18-day-old domain is the loudest signal here, and it says 'proceed with eyes open'.
In plain English
SlideBySide looks like a genuinely useful tool for presenting slides together, and its security setup is fine. But the site is only two and a half weeks old, and nobody is taking credit for building it. Until you know who runs it, treat it as an experiment — don't upload anything confidential, and don't rely on it for important presentations.
Where the score comes from
Strong cryptographic setup: modern TLS, HSTS enforced, and protection against clickjacking. No malware or blacklist flags. Exactly what you'd expect from a properly run web service.
The domain is only 18 days old and the registrant is hidden behind privacy. No about page, team info, or company name anywhere. For a commercial SaaS tool, that's a real gap — you don't know who built it.
No black marks, but also no track record. The domain is too new to have earned any trust signals. A single Hacker News mention doesn't substitute for years of positive operation.
Contact email and legal pages exist, but there's no about page, no social media presence, and no physical address. A legitimate SaaS would typically tell you more about who runs it.
Privacy policy and terms of service are present, which meets the basic bar for a site that may collect email addresses later. No cookie consent was visible, but that's not uncommon for free-tier tools.
Solid technical foundation: Cloudflare CDN, multiple IPs, email authentication set up, and a valid certificate. No obvious hosting weaknesses.
What we checked
Security & Transport
Certificate issued by Google Trust Services
X-Frame-Options: SAMEORIGIN
Site has Content Security Policy configured
No threats detected by Google Web Risk
Site enforces HTTPS via HSTS
Server still accepts TLS 1.0/1.1 from clients that ask for them, which CDNs such as Cloudflare allow by default. Browsers stopped offering these versions in 2020, so visitors connect with TLS 1.2 or later
Cloudflare's malware-blocking resolver (1.1.1.2) answered normally for this domain. These resolvers refuse domains their threat intelligence lists for malware or phishing, and a scam only days old often isn't listed yet. Quad9 gave no usable answer.
Valid certificate, expires in 74 days

Connection uses TLS 1.3
Identity & WHOIS
No About / Team / Company page detected.
Site has a favicon but no social sharing metadata
No dedicated legal-entity disclosure page detected — common and expected outside the EU, but required for commercial sites in Germany, France, Spain, Italy, and other EU jurisdictions.
Homepage has an email address on the site's own domain
Domain created 2026-10-10 (18 days ago) — very new domain, high risk

Website has both privacy policy and terms of service pages
The registration shows a privacy service or redaction notice in place of the owner. Most registrars do this by default since GDPR (2018), for companies as well as individuals, so it hides nothing unusual.
