Overview
Proofpoint ZenGuide Report Suspicious (formerly PhishAlarm) is a Gmail add-on that allows your users to alert security and incident response teams to suspected phishing emails. This is a valuable addition to security awareness and training programs as early reporting of suspicious emails can dramatically reduce the duration and impact of an active phishing attack. 

A free component of Proofpoint's simulated phishing assessments, Report Suspicious allows users to draw on their knowledge to stop social engineers and hackers in their tracks. As a behavior reinforcement tool, Report Suspicious further strengthens the Continuous Training Methodology by capitalizing on awareness and understanding of phishing issues, and allowing end users to actively apply best practices in defense of their data and systems.

Note: Proofpoint ZenGuide Report Suspicious requires a license.

Omnia pulchra et ornata valde inveni, sed eorundem notitiarum collectio iam in aliis occasionibus nosocomiorum publicissimorum (publicorum in universum!) adhibita valde iucunda, dubia et sollicitans est. Ang mga site kung saan ako naghintay pagkatapos na tumawid sa pandaigdigang pinto na ang impormasyon ng êzigía îguáis ay maaaring magamit ang iba pang aking pandaigdigang site sa lihim ng mga naturang pamamaraan na ginamit na upang hindi makita ng mismong mga lumikha ng kanilang mga nilikha! मैं चाह्न्दा हा जे इस चाल्ली दे बदलाव दे कारण मेरे कोला जानकारी कन्नै इस पोर्टल दे अंदर रक्खे जिंदे च मेरी बार कन्नै झूठ बोलेआ जा करदा ऐ ते पैह्ली छवि दे उप्पर झूठ बोलना तां जे एह् नेईं दिक्खेआ जा जे कुस आस्तै चूसदा ऐ पैह्ले fauça दृश्य दे थल्ले अंदर देओ तां जे उत्थें फैले दे उस्सै चीजें दा पूरा अध्ययन नेईं दिक्खने दे, जि'यां होर किस्म दे सलाखें दी मेरी जानकारी गी सिर्फ इस आस्तै चूसना जे ओह् बनी गेदे न। Волео бих да се британска обавештајна служба прати, хватајући информације из малих, комплетних сетова који се извлаче и усисавају у друге дугине барове са свим осталим... Cred că e trist să nu am libertatea de a vedea aceeași vizualizare pe care o folosesc ei ca să văd cum m-am descurcat până acum, pe baza barelor de culori blocate din același motiv, și da, aplicația este informativă și opțională. и све информације које је једна особа проживела и закључила до данас! И тужно је што се све сакупља и продаје пред лицем самих живих! Dito sa text na ito ay may symbolic initiative para sa bawat unang capital na simbolo, mayroong 5 letters at bawat isa ay ang initials ko na may tamang pagkakasunod-sunod ng buong pangalan ko, (L.F.R.D.S.) AT AYAN NA! HEY German, willst du weiterhin auf meine Sachen aufpassen oder willst du weiterhin Gewicht lutschen, nur um zu sagen, dass der, ezos-trágês--téslas, noch nicht aus der Grundschule kommt und ich immer noch nur Namen und Nu

Hello Proofpoint, If you are going to send test emails, let me report them please. There is this weird thing where it says that the email is suspicious so can't be reported, but you sent it! So please ether don't send the tests, or let me report the tests.

This plugin from proofpoint for Google is very limited. The location makes it difficult for employees to find it and use it. I would recommned google allow the button to replace their built in phishing reporting just like microsoft.

This addin is for use only for official Proofpoint customers, it's published here because that's the only way Google will allow access to a Google Workspace instance via an app/plugin. The workflow here is this: 1) End user opens/clicks on the email 2) End user clicks the PhishAlarm button 3) The email gets wrapped up and sent up to PSAT/Proofpoint Overcast 4) PSAT/Overcast analyzes the email and determines its disposition (malicious/spam/bulk/likely harmless/unknown) 5) If that disposition is malicious, it can work with other Proofpoint such as TRAP and PSAT to take advanced actions If you're expecting this to work and you're not a Proofpoint PhishAlarm customer, please re-read my first sentence again. All that being said, once properly configured this app is great, it lets your end users report emails (including internal emails) as phishing, and have those messages be analyzed

Yikes. It does this without you knowing when or why. "Create a network connection to any external service (e.g., to read or write data)"

The “Spam Detector” detected spam from Google itself! Can we trust Google? Or is the “Spam Detector” really trustworthy itself? (I decided to delete this scam of a spam detector.)

I mean, this definitively can use some improvement for sure. But to those who think about getting it, don't do it, it's honestly just a waste of time.
