Comparison Table
DNSFilter
SMBAI-powered DNS filtering with real-time threat and content categorization.
API-driven policy management for groups and allowlists supports automated onboarding and consistent governance.
DNSFilter is a web content filtering service that enforces policies at the DNS layer, which suits networks that want fast blocking without deploying an inline gateway for every flow.
It supports URL categorization, domain allowlists and blocklists, and policy rules tied to users and groups so governance can follow identity boundaries.
Administration includes reporting on blocked activity and audit-friendly change history so administrators can verify enforcement outcomes.
HTTPS visibility depends on deployment choices beyond DNS-only blocking, which limits what can be inspected when traffic never maps to filterable domains.
- +DNS-layer URL category enforcement reduces time-to-block for most browsing
- +User and group policy scoping supports identity-aware governance
- +Built-in reporting shows blocked domains and categories for audits
- +API supports automation for policy updates and provisioning
- –Granular page-level control is limited when URLs resolve to allowed domains
- –HTTPS inspection coverage depends on how endpoints are integrated
- –Category accuracy varies by domain popularity and classification signals
- –High-volume changes require careful change control to avoid policy churn

Cisco Umbrella
enterpriseDNS-layer security and content filtering for enterprise networks.
DNS-layer enforcement that applies URL category policy and threat intelligence to DNS resolutions.
Umbrella provides cloud-managed policy enforcement centered on DNS queries, which helps prevent known bad destinations from resolving into browser sessions. URL categorization drives block and allow decisions, and the platform records web events for filtering reports and investigation. Integration options include connecting enforcement to corporate networks and joining it with other security controls so policy decisions remain consistent.
A tradeoff is reduced visibility into page contents because decisions happen before HTTPS content is available for inspection. Umbrella fits organizations that want fast web risk reduction across roaming users and remote offices. It is also a strong fit when DNS filtering is used as a first line of defense alongside separate HTTPS inspection controls.
- +DNS-based URL policy blocks risky domains before browser sessions start
- +Granular allow and block decisions based on URL category taxonomy
- +Centralized reporting on web requests and filtering outcomes
- +Identity and group policy mapping reduces manual per-site rules
- –Limited content-level control because policy runs before HTTPS inspection
- –Effective coverage depends on consistent DNS routing across networks
- –Change governance can be harder when many groups inherit shared policy
- –Deep application control may require adjacent tooling beyond DNS filtering

How to Choose the Right Web Content Filtering Software
What separates options is how they enforce policy across browsing paths, then record what happened. Look closely at labels like URL categorization and audit logs because they drive the precision of blocking and the ability to prove what users saw.
URL categorization coverage
Why it matters
URL categorization coverage determines whether common “unknown” sites still get classified for the right action. When coverage is shallow, users will route around blocks or hit over-broad decisions.
How to check
In a demo, pick 10 real sites your staff argue about and ask where they land in category decisions. Then try changing policy for one category and confirm it affects those specific domains immediately.
Policy precision granularity
Why it matters
Policy precision granularity matters because web filtering only works when you can target behavior, not just broad categories. More granularity reduces false positives that break legitimate work.
How to check
Request a sample policy editor session. Try setting a rule that blocks one category for a group while allowing a specific domain, then verify precedence by flipping the domain rule.
Enforcement path consistency
Why it matters
Enforcement path consistency shows whether filtering stays uniform when users move between browsers, networks, or device types. If enforcement changes, your policy becomes unreliable mid-day.
How to check
Ask for a walkthrough of where decisions are made for typical flows (office network, home VPN, guest Wi‑Fi, mobile data). Then test the same URL from two environments and confirm the action and category match each time.
User and group policy controls
Why it matters
User and group policy controls determine whether you can align access to roles without manual per-user handling. Strong targeting also supports predictable exceptions.
How to check
Ask to build two groups with different permissions and add one user to each. Verify you can also inherit or override settings at the group level and that changes apply to active sessions.
Audit logs and filtering reports
Why it matters
Audit logs and filtering reports let you verify what was blocked and why. Without clear evidence, you can’t tune policy or handle complaints with confidence.
How to check
Generate a report for a short test window and confirm it includes user identity, timestamp, requested URL, category decision, and final action. Ask whether logs are exportable and what retention period is available.
Threat intelligence freshness
Why it matters
Threat intelligence freshness affects how quickly malicious URLs and suspicious destinations get caught. Stale feeds create delays between real-world risk changes and enforcement.
How to check
During the demo, ask how quickly new detections appear after they enter the system. Then show one recent phishing or malware URL from a public source and confirm the system classifies it with the expected action.
Red flags
- Category changes don’t predictably follow the URL you test
- Group overrides don’t take effect or don’t show precedence
- Audit logs omit the URL or the reason for the action
Fit by situation
- If you manage permissions by role across a mixed staff, prioritize User and group policy controls.
- If your team complains about false blocks on work sites, prioritize Policy precision granularity.
- If you need proof for internal reviews after incidents, prioritize Audit logs and filtering reports.
