Brevilabs LLC · Technology · N/a
Medium risk. 6 critical or high findings in Email security, Security headers and 2 other checks.
Brevilabs LLC operates the website 'Copilot for Obsidian', offering an advanced AI assistant plugin designed to enhance personal knowledge management within the Obsidian note-taking platform. The product targets knowledge workers, researchers, and writers seeking AI-powered assistance integrated directly into their note-taking environment. The business model includes a free tier and paid subscription plans with advanced AI features and lifetime licenses. The company maintains an active presence on GitHub and YouTube, providing transparency and community engagement. Technically, the website is built using modern web technologies including React and Next.js, hosted on Vercel, and incorporates performance and analytics tools from Vercel. The site is well-optimized for SEO, mobile responsiveness, and accessibility, providing a professional user experience. Privacy is emphasized through local data storage and no backend access to user notes, aligning with best practices for personal data protection. Security posture is generally strong with HTTPS enforced and open-source frontend code for transparency. However, the absence of explicit security headers, cookie consent mechanisms, and published security or incident response policies represent areas for improvement. The lack of WHOIS data for the domain introduces some uncertainty regarding domain legitimacy, though the website content and business information appear professional and trustworthy. Overall, the website presents a credible and well-executed product offering with minor gaps in privacy compliance and security transparency. Strategic recommendations include implementing cookie consent, publishing security policies, and verifying domain registration details to enhance trust and compliance.
Scanned
NIS2 Art. 21(2)
This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.
GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.
6 findings rated critical or high. Fix these first.
SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.
Domain is vulnerable to email spoofing
What to do: Implement SPF, DKIM, and DMARC immediately
Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.
Prevents clickjacking attacks
What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"
Controls resources the browser is allowed to load
What to do: Implement a Content-Security-Policy appropriate for your application
These are the privacy signals visitors and data protection authorities look for under GDPR.

Each check with its score, findings and the evidence it collected.
The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted
Findings that cap the score at 49
Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.
Partial scans
When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.
Risk levels
Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.
Leaked records that mention obsidiancopilot.com, from OffSeq Breach.
No leaked records found
Breach holds no records for obsidiancopilot.com right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.
Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
