PhishER Plus | How It Works

Advanced Protection for Evolving Threats

Email threats get more sophisticated every year. Worrying percentages make it past your secure email gateway (SEG) and into your users’ inboxes. Social engineering attacks increasingly target your high-risk users. The 2023 Verizon Data Breach Investigations Report shows email alone is the highest cause of data breaches. Researchers at ArmorBlox recently reported that 56% of all attacks bypass your legacy security filters. The upshot? Legacy email security layers let these digital time bombs slip into the inboxes of your users.

Revolutionary, Proactive Anti-Phishing Defense

PhishER Plus is the most powerful anti-phishing protection available in the world. PhishER Plus is powered by a unique KnowBe4 global threat feed. This triple-validated phishing threat feed automatically blocks phishing attacks before they make it into your users’ inboxes using:

Global Network

KnowBe4's global network of over 10 million highly trained end-users and their PhishER Administrators

Machine Learning

PhishML, a unique AI-model trained on phishing emails that all other filters missed

Threat Intelligence

Human-curated threat intel by KnowBe4’s Threat Research Lab

How PhishER Plus Works

PhishER Plus was developed to help you supercharge your organization’s email security defenses and is an additional final layer after your existing SEG and other cybersecurity layers fail.

PhishER Plus enables a critical workstream to help your IR teams work together to mitigate the phishing threat and is suited for any organization that wants to automatically prioritize and manage potentially malicious messages—accurately and fast! PhishER Plus is available as a stand-alone product or as an add-on option for KnowBe4 customers.

PhishER processes user-reported phishing and other suspicious emails by grouping and categorizing emails based on rules, tags and actions.

PhishML, the custom machine-learning module, analyzes messages and generates confidence values which are used to tag messages.

PhishRIP helps you easily find and quarantine suspicious messages still sitting in mailboxes across your entire organization.

PhishFlip automatically turns defanged phishing emails into training opportunities by flipping them into simulated phishing campaigns.

PhishER saves us a ton of time. The majority of emails reported by users are automatically analyzed by PhishER and automatically removed from inboxes. Without it, I’d have to expand our team because it would be too much for us to manage.
