The problem with network-level filtering
Most companies that allow YouTube and LinkedIn have no meaningful control over what employees see on those platforms. Network-level tools — Cisco Umbrella, Zscaler, Palo Alto, Fortinet Web Filtering — operate at the URL and domain level. For them, youtube.com is either allowed or blocked. There is no middle ground.
This creates a real policy gap. A company might have a clear stance on employees accessing conspiracy content, propaganda, or NSFW material during work hours, but no technical mechanism to enforce it without blocking the entire platform. And blocking YouTube outright is increasingly untenable: the platform is used for product training, onboarding videos, industry conference recordings, and technical documentation. Blocking it means taking away legitimate work tools.
LinkedIn has the same problem in a different direction. It's essential for sales teams, recruiters, and anyone doing business development — but left unmanaged, it's also a significant source of distraction. Endless engagement-bait content and notification-driven browsing consumes time that network logs will show as "LinkedIn" and therefore "allowed."
Blokari fills the gap between "block the platform" and "allow everything."
What Blokari for Business does
Blokari is a Chrome extension that filters content within YouTube and LinkedIn — not at the URL level, but at the content level. It reads the page after it loads, identifies channel or profile information in the DOM, and hides posts, videos, and recommendations that match blocked categories.
This means employees keep full access to the platforms. A developer can still watch a technical tutorial on YouTube. A salesperson can still research a prospect on LinkedIn. What they won't see is conspiracy content, violent extremism, gambling promotions, propaganda, or whatever categories your IT policy specifies.
Key capabilities for corporate deployment:
- 14 content categories — violence, extremism, conspiracy, gambling, NSFW, AI slop, propaganda, clickbait, engagement bait, recruiter spam, humblebrag, kids-unsafe content, scam/fraud, and more. Each can be enabled or disabled independently.
- 3 filter levels per category — blur with badge, block deceptive content, or block all matched content. Different departments can have different levels of restriction.
- Curated blocklists maintained by OSINT specialists — lists are updated based on ongoing research, not just user reports. Channels and profiles are reviewed before being added.
- Chrome Enterprise compatible — the extension can be force-installed and configured via Chrome Enterprise policy (managed Chrome or Chromebook environments). User cannot disable or uninstall force-installed extensions.
- Offline-first — filtering works even when the sync server is unreachable. The blocklist is cached locally and applied from IndexedDB. No dependency on network connectivity to Blokari's servers for day-to-day operation.
- No user data collection — Blokari does not read or transmit browsing content, search queries, or video titles to its servers. It checks channel IDs against a local cache.
Use cases
Corporate offices
Block conspiracy, extremism, and NSFW categories on employee workstations. Keep YouTube and LinkedIn accessible for legitimate work while eliminating content that creates HR or compliance risk.
Schools & universities
Safe YouTube on student Chromebooks without Restricted Mode (which blocks too much legitimate educational content). Enable parental-style filtering for student accounts managed via Google Workspace for Education.
Government agencies
Block propaganda and disinformation feeds for employees who need social media access for monitoring or communications work. Particularly relevant for agencies in regions with active information warfare.
Call centers
Remove distracting and inappropriate content on shared workstations where multiple employees use the same browser profile or where personal browsing is allowed during breaks.
How it works — deployment in 3 steps
Blokari is a standard Chrome extension. For individual users, installation takes 30 seconds. For enterprise deployment, the process follows standard Chrome Enterprise policy management.
For environments without Chrome Enterprise (e.g., BYOD policies or unmanaged devices), Blokari can still be deployed as a recommended extension with pre-set defaults. Users install it voluntarily and receive the organization's configuration via a shared settings link.
Why not just block YouTube?
This question comes up in every corporate content policy discussion. The answer has changed significantly in the past five years.
YouTube is no longer purely an entertainment platform. It is now a primary channel for professional and educational content:
| Use case | Block YouTube | Filter with Blokari |
|---|---|---|
| Employee training videos | Blocked | Available |
| Product demo recordings | Blocked | Available |
| Conference talks and keynotes | Blocked | Available |
| Conspiracy and extremism content | Blocked | Blocked |
| NSFW and gambling content | Blocked | Blocked |
| Entertainment / distraction | Blocked | Partially filtered |
LinkedIn is even more clear-cut. A sales team that can't access LinkedIn is a sales team operating with a major constraint. Recruiters, business development professionals, and executives use LinkedIn daily for legitimate work. Blocking it to avoid distraction is trading a small problem for a large one.
Filtering within the platform preserves productivity while eliminating the content that creates compliance risk or wastes time. It's not all-or-nothing.
