The problem

Every day without protection,
your contacts are being harvested

📧

Email Harvesting
One exposed email on any page generates 100+ spam messages per day. Once bots find it, it never stops.

📱

Robocall Floods
Exposed phone numbers get sold to robocall and SMS spam networks within hours of discovery. Your business line becomes useless.

📬

Junk Mail & Identity Risk
Visible physical addresses feed junk mail campaigns and worse — identity theft operations targeting businesses and individuals.

🔍

Bots Are Thorough
Scrapers crawl every post, every widget, every page builder block. One unprotected contact anywhere = total exposure.

🤖

AI-Powered Scrapers
Modern scrapers use AI to decode basic obfuscation in seconds. HTML entities and simple encoding — the industry standard — are effectively useless.

⏱️

It Compounds Over Time
Once your contacts are in spam databases they’re resold, redistributed, and recycled indefinitely. Prevention is the only solution.

Why other plugins fail

Manual shortcodes aren’t a
strategy. They’re a liability.

⚠ The Critical Flaw in Every Shortcode-Based Plugin

Email Address Encoder, Neotrendy, Email Encoder Bundle — they all require you to manually wrap every single contact on your site. Hundreds of posts. Dozens of widgets. Every page builder block. Miss just one email in an old post from three years ago, and scrapers find it. One gap = total failure.

Single-layer HTML entities — decoded by modern scrapers in milliseconds
Manual shortcodes require updating every post, widget, and page builder block yourself
No phone number or address protection — only emails covered
No active defense — they hide contacts but never catch or block the scrapers doing the harvesting
No coverage audit — no way of knowing what you’ve missed
One unprotected contact anywhere on your site defeats the entire strategy

What Shield Pro does

Every feature built to
close the gaps
others leave open

🔐

Military-Grade Encryption
Encryption generated specifically for your installation — bots see only unreadable data, never the real thing. Your visitors see normal contact info with one click.

🪤

Scraper Trap™ Defense
Hidden honeypots invisible to humans catch bots the moment they probe your site. Their IP is blocked instantly and automatically — they can’t access a single page ever again.

🔒

Invisible to Every Automated Scraper
Bots harvest raw HTML — and your contacts aren’t there. What they see is unreadable encrypted data with no practical path to your actual contact information.

🛡️

Automatic IP Blocking
The moment a scraper triggers a trap, they’re blocked. Choose your duration: 1 hour to permanent. Full audit dashboard shows every blocked IP with timestamp, location, and trigger.

🔔

Real-Time Email Alerts
Instant notifications when scrapers are caught. Know exactly when your site is under attack and watch your defenses working in real time.

👆

Click-to-Reveal Buttons
Add an optional human-verification layer — contacts stay hidden behind a customisable button until clicked. 8 professional button styles to match your brand.

Defense architecture

Three independent layers.
Complete coverage.

1
Military-Grade Encryption
Passive

Encryption generated specifically for your installation — bots harvesting your HTML find only unreadable data. Every contact is encrypted before it ever reaches a browser. Your contacts are simply invisible to automated scrapers.

2
Scraper Trap™ Active Defense
Active

Hidden honeypots catch bots red-handed the moment they probe your site. Once caught, their IP is blocked from every page — not just the one they triggered. Configurable block duration, custom block pages, whitelist management, and a full dashboard of every catch. You’re not just hiding — you’re fighting back.

Independent proof

We ran it alongside
Wordfence. The numbers
speak for themselves.

We installed Shield Pro and Wordfence on the same site at the same time and let them run. Wordfence is a trusted, industry-standard firewall. We’re not here to replace it. We’re here to show you what’s happening upstream — before any firewall ever gets involved.

Wordfence
Industry-standard WordPress firewall — same site, same 30 days
0
Blocks recorded
VS
WhoKnew Shield™
Upstream honeytrap layer — same site, same 30 days
491+
224 via Scraper Trap™ · 267 via Intelligence™ network
Wordfence showed zero attacks — not because the site was quiet, but because Shield had already blocked 491+ threats before they reached the firewall: 224 caught directly by Scraper Trap™, plus 267 more blocked by the WhoKnew Intelligence™ network. That’s not a conflict between two tools. That’s two tools doing exactly what they’re supposed to.

🪤

Catch them first
The honeytrap fires the moment a bot ignores robots.txt — before it maps your site, before it finds a weakness, before it attacks anything.

🔒

Lock them out permanently
One trigger = blocked from your entire site. Repeat offenders auto-promote to permanent bans. The IP never gets a second chance.

🌐

Block 15M before they arrive
WhoKnew Intelligence™ blocks 15 million verified hostile IPs the moment you activate — before a single request hits your server.

New Feature
Silent Contact™ · The ultimate layer

Your email, phone, and address
don’t have to exist on your website.

Military-grade encryption hides your contacts from bots. Silent Contact™ goes further — it removes them from your HTML entirely.
Every email address, phone number, and physical address is rendered as a transparent PNG image, generated fresh on your server, matching your site’s exact font and color.
Visitors see perfectly readable, fully clickable contact info. Bots, scrapers, and data harvesters find absolutely nothing.

👁 What scrapers see in your source code
<img src=“data:image/png;base64,iVBOR…”
alt=“”
class=“wks-png-img”
draggable=“false” />
✗ No email. No phone number. No address. Nothing to harvest.

👤 What your visitors see on screen

New York, NY 10001
✓ Pixel-perfect. Fully clickable. Completely invisible to bots.

📧
Email Addresses
Rendered as a PNG that looks identical to your normal text — and still opens your mail client when clicked. Spam harvesters find an image. Your visitors get a working mailto link.
📞
Phone Numbers
Display any format you like — dashes, dots, parentheses, even vanity numbers like 1-800-FLOWERS. Silent Contact™ renders the display as an image and still dials the correct digits when tapped on mobile.
📍
Physical Addresses
Multi-line addresses rendered perfectly, with an optional Google Maps link so visitors can click straight to directions. Data brokers and junk mail scrapers find nothing — not a single character of your address exists as text.

✓ PNG rendering for email, phone & address
✓ 15 bundled professional fonts
✓ Full style control — font, size, weight, color
✓ OCR noise layer — invisible to humans, disruptive to bots
✓ Vanity phone number support (1-800-FLOWERS dials correctly)
✓ Google Maps link option for addresses
✓ Live shortcode generator with font preview
✓ Zero external dependencies — all generated server-side

Three shortcodes. Every contact type covered.
📧 Email address
[wks_png_email font=“inter” size=“16” weight=“400” color=“#333333”]389d54b8@0a482b3a.com[/wks_png_email]
📞 Phone number
[wks_png_phone font=“inter” size=“16” weight=“400” color=“#333333”]395397e1@36f04892.com[/wks_png_phone]
📍 Physical address
[wks_png_address font=“inter” size=“16” color=“#333333” link=“true”]123 Main Street\nNew York, NY 10001[/wks_png_address]
Don’t write shortcodes by hand — the Silent Contact™ tab in your Shield Pro dashboard generates them for you. Pick your font, size, and color, copy the shortcode, drop it anywhere on your site.

Every Shield Pro site
protects yours.

Shield Pro connects to a community-driven threat network built by every participating WordPress site. Scrapers caught by any site — verified by multiple independent sources — join a shared blocklist. Your site blocks them automatically, before they send a single request.

Zero-effort switching

Shield Pro takes over
your old shortcodes —
and makes them stronger.

Your old plugin was using those shortcodes to apply basic obfuscation. Shield Pro intercepts the exact same shortcodes and runs military-grade encryption through them instead. Your posts, pages, and widgets don’t change. The protection underneath them does — completely.

01
Activate Shield Pro
Shield Pro immediately registers your old plugin’s shortcodes as its own — hijacking them and routing through military-grade encryption.

⚡ 30 seconds

02
Deactivate old plugin
Turn it off. Shield Pro already owns those shortcodes. Every page, post, and widget using them is instantly upgraded to real protection.

🔄 5 seconds

03
Every shortcode encrypts
Zero find-and-replace. Zero broken pages. Zero downtime. Hundreds of posts upgraded in one click — with protection your old plugin was never capable of.

🛡️ Instant upgrade

I’m getting ready to launch a new blog and was looking to add an extra layer of protection from bots and scrapers harvesting info from my site. I downloaded the free version of this plugin to try it out and quickly made the decision to upgrade to the Pro version. It’s been worth every penny. I’m very knew to blogging, but the setup for this plugin was very clear and easy to follow. I like that I don’t have to be fluent in code to customize the settings. It’s already blocked at least 8 suspicious ip addresses that were trying to access my site. I love how easy the dashboard is to navigate and see my daily reports. I had a little bit of a learning curve figuring out which settings to turn on, but WhoKnew’s tech support and knowledge base helped me every step of the way. Who Knew Shield is a hidden gem here in the plugin store.

Thank you so much for this — and we have a confession to make. Your comment about the learning curve with settings stayed with us. We went back and built a one-click onboarding setup that automatically enables the recommended settings for new users. It's live now. You asked for it without even knowing it. We really appreciate you taking the time to share your experience

Been using this for about two months. The combination of hiding contact info from scrapers and actively trapping the bots with Scraper Trap is smart. One approach is passive, the other is active—together they work great. Intelligence ties it together with the geo data and timeline. Genuinely well-built plugin.

 by Chad C.


just works. spam calls are way down. 5 stars

 by Kevin T.


Does a solid job stopping scrapers from harvesting our contact info—less phone spam, fewer spam texts, less email spam. The physical address protection is there too though honestly scammers don't use that the same way. The honeypot and intelligence network are the standout features for me. Quick migration, good support. Would give 4.5 if I could.

 by Zara P.


Tried two other solutions before this. Both were either too complicated, cost 5 times more, or didn't actually work. Shield worked out of the box and auto-detect saved me from having to go through 200 plus pages. The click-to-reveal looks clean and doesn't annoy real users. Scraper Trap is doing its job in the background.

 by Daniel O.


Switched from Email Encoder Bundle. Shortcodes recognized automatically, zero broken pages. The intelligence dashboard is a serious upgrade—we can see who's being blocked and from where. Less phone spam and email spam since our contact info stopped being harvestable. No regret.

 by Maya D.


We're a small nonprofit, and nobody here has much tech bandwidth. This was easy to set up, doesn't need babysitting, and our main email and phone number are finally protected. The dashboard shows it's working. That's all we needed.

 by Viktor S.


Good plugin, does what it promises. Shortcode compatibility made migration easy. The trap is working—see the blocks in the dashboard. Took off one star because I'd like an option to export the intelligence data but it's not a dealbreaker.

 by Isabella N.


Our industry attracts a lot of bots. This is the first tool that's actually made a dent. Scraper Trap actually catches them. WhoKnew Intelligence helps since the community blocklist is pretty extensive, and our contact info stays out of harvester databases. But honestly, the security this provides is next level for the price.

 by Alex R.


Free version is great on its own. Upgraded to Pro for the scraper trap and I can see it catching bots in real time. Emails stopped showing up in spam lists I think
