Cisco Umbrella Alternatives for HTTPS Inspection: DNSFilter vs. dope.security

The rest of this guide unpacks each row, starting with the architectural fork that drives almost every other difference in the table.

Every DNS lookup exposes exactly one piece of information to a filter sitting at the resolver: the domain name being requested. It does not expose the URL path, query string, uploaded file, form data, or rendered page content that follow. Once the domain resolves and the browser opens its HTTPS connection, that entire exchange is encrypted end to end between the browser and the destination server. A DNS-only filter has no way to look inside it.

Here is a concrete example of why that matters. Attackers increasingly host phishing kits and malware droppers on multi-tenant, shared-hosting platforms, subdomains of services like public app-hosting providers, static site hosts, or file-sharing platforms, where thousands of legitimate customers share the same base domain. Because the base domain (for example, a shared hosting provider's root domain) also serves enormous amounts of legitimate traffic, a DNS-only vendor generally cannot block the entire domain without breaking access for legitimate tenants, so it can only act once the specific malicious subdomain or path has been individually identified and added to a reputation feed. Until that happens, the phishing page resolves cleanly and loads normally under a DNS-only control, because the DNS-only tool never looks past the domain name to see which specific page or path is malicious.

An on-device SWG that decrypts and inspects the actual HTTPS request locally can, in principle, evaluate the full URL path, the page's content, and behaviors like a credential-harvesting form submitting to an unusual endpoint, and act on that single malicious page without needing to block the shared base domain at all. That is the specific gap dope.security's own comparison content calls out, arguing that "DNS resolution is not web inspection" and that Cisco's DNS-plus-proxy model still requires a backhaul through Cisco data centers to get comparable visibility, adding latency for distributed workforces.

The fair counter-argument, which Cisco and DNSFilter would both reasonably make, is threefold. First, the large majority of malicious traffic is still stopped at the domain or IP reputation stage before a browser ever renders a page, so DNS-layer blocking remains a high-leverage, low-latency control even if it is not a complete substitute for full web inspection. Second, Cisco already sells full HTTPS inspection through its SIG Essentials and SIG Advantage tiers for organizations that need it, at the cost of additional complexity and the backhaul latency dope.security criticizes. Third, an on-device agent that performs local SSL inspection only protects devices where that agent is installed and running correctly; a DNS-only control protects any device pointed at the resolver, managed or not.

A second, related gap worth testing directly in a proof of concept is DNS-over-HTTPS (DoH) bypass. Modern browsers (Chrome, Firefox, Edge) can be configured by an end user to use their own encrypted DNS resolver instead of the network's, which routes around a DNS-layer control entirely unless the vendor's roaming client actively detects and overrides that browser setting by policy. Both Cisco Umbrella and DNSFilter address this in their roaming clients, but it requires ongoing browser policy management and is a control that can silently fail if a policy update lapses. An on-device SWG is not defeated by browser DoH settings in the same way, since it inspects traffic at the OS or network-stack layer rather than depending on which DNS resolver the browser chose, though it introduces its own dependency on TLS interception certificates and local firewall rules being correctly maintained.

Cisco Umbrella supports three deployment models: network-level DNS forwarding from an existing firewall or router, a virtual appliance for Active Directory site-to-user mapping, and the Cisco Secure Client Umbrella module for roaming devices off-network. The standalone legacy Umbrella Roaming Client is in end-of-life, and Cisco is actively migrating customers toward Cisco Secure Access, its consolidated SSE platform. Organizations that add the SIG Essentials or SIG Advantage tiers get a cloud-delivered proxy, firewall, CASB, and (at the Advantage tier) remote browser isolation, with flagged traffic backhauled through Cisco's global data centers for full inspection.

DNSFilter is a cloud-delivered resolver deployed via network-level DNS forwarding, or through DNSFilter's own site/relay infrastructure for on-premises networks, plus roaming clients for Windows and macOS (Pro tier and above) and iOS and Android (Enterprise tier) that enforce policy off-network and encrypt DNS queries in transit. DNSFilter does not offer a proxy or SWG tier; the product stays DNS-only across its entire line, which keeps deployment simple but caps what it can ever see.

dope.security deploys as a single lightweight agent, dope.endpoint, installed through existing MDM tooling such as Intune or Jamf. The agent performs SSL inspection, URL filtering, malware detection, cloud application control, and DLP locally on the device, which the company markets as "fly direct" architecture with no data-center backhaul. Because the product's value proposition depends on the agent being present, it does not have a comparable network-level deployment path for devices that cannot run an agent, such as IoT devices, printers, servers, and guest Wi-Fi, which is a real coverage gap worth weighing against its HTTPS visibility advantage.

Cisco Umbrella has the deepest integration ecosystem of the three, reflecting its market age and Cisco's broader security portfolio. It supports native and partner SIEM integrations (Splunk among them) through the Umbrella reporting API, provisions identities from Azure AD/Entra ID and Okta via SCIM, and deploys through the same endpoint management tools (Intune, Jamf, SCCM) that already push Cisco Secure Client. Note that an on-premises Umbrella AD connector is still required for virtual appliance or IP-to-user mapping deployments, since Entra ID and Okta do not themselves store private IP-to-user mappings.

DNSFilter's integration story is narrower but functional for its price point: SIEM data export to Amazon S3 or Splunk is available as a $0.25 per user per month add-on across all tiers, Active Directory support and a Zapier integration ship at the Pro tier, and API access is available for teams that want to build custom workflows. Roaming clients are deployed silently through standard RMM or MDM tooling.

dope.security's integration surface is the smallest of the three, consistent with being a Series A company (founded 2021, roughly $23.9M raised as of its last disclosed round). Deployment runs through MDM (Intune, Jamf), and log export is available via its console and API, but it does not yet have the breadth of pre-built SIEM and identity-provider connectors that Cisco has built over more than a decade in the market. For teams with a mature SOAR pipeline and multiple existing Cisco integrations, that gap is worth quantifying directly rather than assuming parity.

DNS-only deployments are generally the lowest-friction of the three to roll out. Pointing an office network's DNS at Cisco Umbrella or DNSFilter and validating a block page can be done in minutes, and both vendors' roaming clients are designed for silent, unattended installation via RMM or MDM to remote endpoints. Policy management is also comparatively simple: category-based blocking, allow/deny lists, and identity-based policy tied to AD or Entra ID groups, without the certificate and interception configuration a proxy or on-device agent requires.

dope.security's on-device agent asks more of both the endpoint and the rollout process. Because it performs local SSL/TLS interception, it needs a trusted root certificate deployed to every managed device (typically pushed via the same MDM tooling used for the agent itself), and policy changes need to account for cloud application control and DLP rules in addition to URL categories. This is not necessarily more effort in absolute terms, MDM-based certificate and agent deployment is a well-understood pattern, but it is a different and slightly heavier rollout than pointing a network's DNS at a new resolver.

Cisco's SIG Essentials and SIG Advantage tiers sit in between: they add proxy-based HTTPS inspection with its own certificate deployment requirements, on top of the DNS-layer policy Cisco Umbrella already manages, which means teams adopting the full SIG stack take on operational complexity closer to dope.security's than to DNSFilter's DNS-only model.

Of the three vendors, only DNSFilter publishes list pricing directly on its website: a Core plan at $1.00 per user per month (annual billing) or $1.15 (monthly billing), a Pro plan at roughly $1.80 to $2.30 per user per month, and an Enterprise plan at roughly $2.70 to $3.00 per user per month, each with a monthly minimum. SIEM data export is a $0.25 per user per month add-on across all tiers.

Cisco does not publish Umbrella or Secure Access list pricing on cisco.com. Figures circulating on procurement and reseller sites suggest DNS-only tiers landing somewhere around $2 to $6 per user per month and full SIG tiers landing somewhere around $6 to $13 per user per month, with add-ons and premium support pushing some enterprise deployments higher, but these are third-party estimates rather than vendor-published numbers, and they should be confirmed with your own account team before budgeting against them.

dope.security does not publish pricing publicly; it is quote-based, which is typical for an agent-based SWG vendor at its size and stage. Do not treat any figure you see cited for dope.security online as an official list price without confirming it directly with the vendor.

Because only one of the three vendors has genuinely public, vendor-confirmed pricing, treat any side-by-side dollar comparison you find, including the ranges above, as a starting point for a conversation with sales, not a number to build a budget around.

Cisco Umbrella. Strengths: Talos-backed threat intelligence, the broadest SIEM and identity-provider ecosystem of the three, and a credible path to a full SSE deployment (Cisco Secure Access) for organizations that eventually want one vendor across DNS, web, and CASB. Limitations: full HTTPS coverage requires the SIG upgrade and its data-center backhaul, which reintroduces the latency dope.security markets against; legacy Umbrella SKUs are being sunset in favor of Secure Access, adding migration planning overhead; and list pricing is not published, which complicates budgeting.

DNSFilter. Strengths: transparent published pricing, a capable roaming client with granular reporting and SIEM export, and AI-based content classification that can categorize newly registered domains without waiting on a static reputation feed. Limitations: it is DNS-only across its entire product line with no proxy or SWG option, so an organization that later concludes it needs HTTPS inspection will need a second, separate product rather than an upgrade path within DNSFilter; and its SIEM/identity integration ecosystem is smaller than Cisco's.

dope.security. Strengths: it directly closes the HTTPS/URL visibility gap this article centers on, performing full TLS inspection, URL filtering, and DLP locally without backhaul latency, and it bundles shadow SaaS and shadow AI application discovery into the same agent (for a deeper look at that specific problem, see our shadow IT discovery and management guide). Limitations: coverage is limited to devices running its agent, so IoT devices, servers, guest Wi-Fi, and other unmanaged endpoints are not protected without a separate control; it does not publish pricing; and as a smaller, newer company, its SIEM and identity-provider integration list is thinner than Cisco's. It is also worth noting that the "DNS-only is blind" framing used throughout this comparison originates primarily from dope.security's own marketing content, which is a reasonable business case for them to make but is exactly the kind of vendor claim worth validating independently in your own proof of concept rather than accepting at face value.

Cisco Umbrella fits organizations already standardized on Cisco networking and security infrastructure that want Talos-backed reputation data feeding an existing Cisco-centric SOC, and that have a credible medium-term plan to consolidate onto Cisco Secure Access rather than staying on legacy Umbrella SKUs indefinitely.

DNSFilter fits budget-conscious SMB and mid-market IT teams that want predictable, transparent per-user pricing and solid roaming client coverage for a primarily domain-level filtering need, without paying for or operationally managing a full SWG they have not established a need for.

dope.security fits distributed or remote-first workforces on centrally managed devices whose risk assessment has concluded that domain-only blocking misses too much, whether that is malicious content on shared-hosting domains, shadow SaaS and AI tool usage, or in-app data exfiltration, and that are willing to run a real proof of concept on battery and performance impact before committing, given the vendor's smaller scale and newer market presence.

If your organization already runs a full Security Service Edge or SASE platform, such as Zscaler, Netskope, Palo Alto Networks Prisma Access, or Cisco Secure Access itself, a dedicated standalone protective DNS or on-device SWG purchase is usually redundant. Those platforms already perform DNS-layer filtering as one component of a broader web, cloud, and data-protection inspection stack, so layering a second, separate protective DNS vendor on top typically adds cost and a second policy set to reconcile without meaningfully improving coverage.

The narrow exceptions are DNS resilience or failover requirements that are deliberately kept independent from your primary SSE vendor, and organizations with simple, non-roaming content-filtering needs (small offices, school networks with mostly on-premises devices) for whom a full protective DNS product, let alone an on-device SWG, is more capability than the actual risk profile calls for. In both cases, a lighter-weight or already-bundled option is usually the better fit than adding a third vendor to the stack.

Run these checks with a pilot group before signing a multi-year contract with any of the three vendors.
