What Do Proofpoint Tools Do?
Proofpoint tools scan incoming emails for known security threats like spam, phishing, and malware. When suspicious content is detected, the email is quarantined, allowing users to decide whether to release or block it.
Quarantined items are sent via a separate email called a Quarantine Digest, providing options to:
Release the email to the inbox.
Preview the content safely in a browser window.
Block the sender to prevent future communication.
This extra layer of security gives users control over potentially harmful emails before they reach the inbox.
Essential Things To Know About Using Proofpoint Tools
1. What Should I Do When I Get a Proofpoint Quarantine Digest in My Email Inbox?
Step-by-Step Guide:
Open the Proofpoint Quarantine Digest email.
Preview any quarantined email by clicking the "Preview" link.
3- Review sender details: email address, subject, and delivery time.
Choose an action:
Release: Deliver the message to your inbox.
Release & Approve: Deliver and allow future messages from this sender.
Block: Prevent all future emails from the sender.
2. What If I Accidentally Block an Email and Want It Back?
You can recover blocked emails within 30 days:
Visit Proofpoint Login
Enter your username and password.
Navigate to Tools > Log Search.
Enter search criteria (date, sender, subject) and search.
Select the email and click Release or Report as False Negative to restore it.
3. How to Unblock an Email Address
To reinstate a blocked sender:
Log in to Proofpoint
Click Allow/Block Sender Lists in the left panel.
Move the blocked email address to the Safe Sender List.
Click Save.
4. Do I Need an App to Use Proofpoint?
No. Proofpoint is a web-based security solution. It works automatically in the background, scanning emails for cyber threats.
5. Can I Use Proofpoint to Encrypt Outgoing Emails?
Yes! You can easily encrypt sensitive emails:
Compose a new email in Outlook.
Type [encrypt] at the start of the subject line (e.g., [encrypt] Financial Report).
Send the email as usual. Proofpoint will automatically encrypt the message.
You will receive a confirmation email once the message is encrypted and sent.
Note: Recipients will receive a notification to view the encrypted email through their Proofpoint account.
6. How Do I Restore a Blocked Email Sender?
To allow a sender you previously blocked:
Log in to Proofpoint
Go to Allow/Block Sender Lists.
Move the sender from the Blocked Sender List to the Safe Sender List.
Click Save to confirm.

Dummy Scenario --
Company: XYZ InnovationsEmployee: David (Sales Team)Email: david@xyzinnovations.com
How does Proofpoint Essentials block harmful emails?
David receives an email from finance@secure-payments.com with the subject "Pending Invoice - Action Required". Proofpoint quickly detects that the sender's IP address is associated with phishing campaigns. The system blocks the connection and temporarily blacklists the sender’s IP. David never sees this phishing attempt, and the attacker gets a bounce-back notification.
How does spam and virus filtering work?
David gets another email from promo@freelaptops.net with the subject "Congratulations! You’ve Won a Free Laptop!" and an attachment labeled Claim_Prize.zip. Proofpoint scans the attachment and identifies it as a virus. The email is immediately moved to Quarantine, and David receives a daily quarantine summary. After reviewing the flagged email, David decides not to release it.
What happens if a legitimate email is mistakenly blocked?
A trusted vendor, supplier@techpartners.com, sends David a large product catalog in .pdf format. However, due to file size restrictions, the email is quarantined. David logs into the Proofpoint user portal, finds the email in the quarantine folder, and clicks "Release" to have it delivered to his inbox. Proofpoint updates its filtering rules for similar future emails.
How does Proofpoint handle server downtime?
XYZ Innovations experiences unexpected server downtime during a system upgrade. Meanwhile, a client, client@globalenterprises.com, sends David a contract for signature. Proofpoint detects the server issue and automatically spools the email to its backup server. David accesses the contract through the Emergency Inbox without interruption. Once the server is back online, the spooled email is delivered to his regular inbox.
Can users recover deleted or lost emails?
David accidentally deletes an important email from events@techsummit.com about an upcoming conference. He logs into the Proofpoint portal and uses the Instant Replay feature to resend the email directly to his inbox.
How can administrators monitor and improve email security?
The IT administrator at XYZ Innovations, Emma, notices suspicious email activity. She logs into the Proofpoint admin dashboard and discovers that over 300 phishing emails from alert@fakebanking.com were blocked in the past week. Emma updates the spam filters and blocks similar domains to enhance security.
How Proofpoint Essentials Handles Incoming Emails
Proofpoint Essentials carefully scans every email to protect your organization from harmful content while ensuring important messages are delivered. The system follows a specific step-by-step process to filter emails effectively.
-----------------------------------------------------------------------------------------------------------------------------
1. Connection Layer (First Line of Defense)
IP & Domain Check: When an email arrives, Proofpoint checks the sender's IP address or domain to see if it's already flagged as malicious or trusted.
Attack Detection: It monitors for suspicious activity like:
Email Bombs (overwhelming the inbox with emails)
Directory Harvest Attacks (guessing valid email addresses)
Spam Floods
Virus Outbreaks
Action: If a threat is detected, the system blocks the connection and sends an error message back to the sender.
2. User Validation
Proofpoint checks if the recipient is a registered user or has an alias.
If the user is registered, the email continues to the next step.
If not, the email is either rejected or handled based on the company’s SMTP Discovery settings.
3. Virus Blocking
The email and its attachments are scanned for viruses.
If a virus is detected, the email is blocked and the event is logged.
4. Attachment Defense (If Licensed)
Scans attachments using Proofpoint’s Attachment Reputation Service.
Malicious attachments are blocked and logged.
5. Message Size Check
Emails larger than 100MB are automatically rejected.
6. Sending Limit Control
To prevent misuse, senders are limited to:
100 emails every 10 minutes
500 emails per day
If limits are exceeded, emails are bounced.
For larger campaigns, Proofpoint suggests using email marketing services or requesting a limit increase.
7. Custom Filters
Emails are checked against custom rules set by your company.
These rules can apply to individual users, groups, or the entire organization.
8. Sender Lists (Approved/Blocked Senders)
Emails from approved senders are allowed through.
Emails from blocked senders are either blocked or quarantined.
9. Spam Filtering
Emails go through spam filters that check for junk mail.
If the spam score exceeds a set threshold, the email is quarantined.
10. URL Defense (If Licensed)
Any web links in the email are rewritten to protect against malicious websites.
11. Final Delivery
If the email passes all checks, it’s delivered to the recipient’s inbox.
Why This Process Matters:
Security First: Emails with viruses or malware are blocked immediately, even if they come from an approved sender.
Efficient Filtering: Legitimate emails are delivered, while harmful ones are stopped.
Customizable Protection: Companies can set custom rules to control what gets through
----------------------------------------------------------------------------------------------------------------------
