Features & Capabilities

Investigate reported phishing emails in seconds. AI verdicts, threat intel, sender forensics, and safe link preview.

Your email gateway catches most threats. But what about the emails users report as suspicious?

PhishSight gives security teams and IT admins a fast, thorough way to investigate reported phishing emails — without leaving Gmail.

THE PROBLEM Every "Is this phishing?" report from an employee means context-switching between tools: checking headers in one tab, looking up domains in another, running URLs through VirusTotal, and manually piecing together a verdict. It takes 10-15 minutes per email, and most turn out to be false positives.

THE SOLUTION PhishSight analyzes the full email in seconds and delivers a clear verdict with the evidence to back it up:

• AI-Powered Verdict — Machine learning classifies the email as Clean, Suspicious, or Malicious with a confidence score and plain-English explanation.

• Sender Forensics — SPF, DKIM, and DMARC authentication results at a glance. Domain age, registrar, and reputation checks. Detects spoofing, lookalike domains, and display name deception.

• Threat Intelligence — URLs checked against PhishTank, URLhaus, and VirusTotal feeds. Flags URL shorteners, redirect chains, and suspicious link-text mismatches.

• Header Analysis — Routing path visualization, authentication chain verification, and timing anomaly detection. See exactly where an email came from.

• SecureView Safe Preview — Open suspicious links in a disposable browser sandbox. Inspect landing pages without exposing your machine or network. Session auto-destructs when you're done.

• Content Analysis — Urgency language scoring, action keyword detection, attachment risk assessment, and brand impersonation checks.

Is PhishSight Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

PhishSight requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details
  • Critical Grants access to browser tabs, which can be used to track user browsing habits and history, presenting a privacy concern.

  • Medium ******* ******* ************* ***** *** ** ******* *** **** ******* ****** ******** *******
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

PhishSight may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
