The real buying decision is how well a platform connects business data, respects existing permissions, retrieves useful evidence, and turns that information into reliable answers.<\/p>\n\n\n\n<p>Glean is one of the best-known platforms in this category, but it is not the only option. Depending on your deployment requirements, data architecture, search workload, and budget, a different enterprise AI search platform may be a better fit.<\/p>\n\n\n\n<p>This guide compares Glean, Dashworks, Onyx, Elastic, Vectara, and Coveo across the areas that matter most in an enterprise deployment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-enterprise-ai-search-solves\">What Enterprise AI Search Solves<\/h2>\n\n\n\n<p>Traditional workplace search requires employees to remember where information lives before they can find it. Enterprise AI search changes that model by allowing employees to search across multiple business systems and receive answers based on the information they already have access to.<\/p>\n\n\n\n<p>A typical enterprise environment might contain knowledge across Slack, Google Drive, Microsoft 365, Confluence, Jira, Salesforce, GitHub, and internal databases.<\/p>\n\n\n\n<p>The challenge is not simply connecting those systems. A useful workplace search platform also needs to understand permissions, retrieve the right information, and provide enough source context for employees to judge an answer. This is also part of the broader problem of <a href=\"https:\/\/www.tooljunction.io\/blog\/best-llm-security-tools-enterprise\">enterprise AI security<\/a>.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.glean.com\/platform\/connectors\" target=\"_blank\" rel=\"noopener\">Glean<\/a> currently advertises more than 275 out-of-the-box connectors, permission inheritance and enforcement, and real-time synchronization of data and permissions. <\/p>\n\n\n\n<p>That gives us a useful baseline for comparing the alternatives.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"connector-coverage\">Connector Coverage<\/h2>\n\n\n\n<p>Connector count is an easy number to compare, but it can be misleading.<\/p>\n\n\n\n<p>What matters is whether a connector captures the data, metadata, permissions, and freshness that the organization actually needs.<\/p>\n\n\n\n<p>A company might have hundreds of applications but rely heavily on ten systems for operational knowledge. A platform with fewer connectors can therefore be more useful if those integrations are deeper and easier to maintain.<\/p>\n\n\n\n<p>When evaluating an enterprise AI search platform, check:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Which applications have native connectors?<\/li>\n\n\n\n<li>Are permissions synchronized from the source?<\/li>\n\n\n\n<li>How frequently is content updated?<\/li>\n\n\n\n<li>Are custom connectors supported?<\/li>\n\n\n\n<li>Can the platform handle on-premise or private data sources?<\/li>\n\n\n\n<li>Does the connector support the content types your teams actually use?<\/li>\n<\/ul>\n\n\n\n<p>Glean has the broadest published connector footprint among the products compared here, while Onyx focuses on a smaller connector ecosystem with an emphasis on open deployment and customization. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"permission-aware-retrieval\">Permission-Aware Retrieval<\/h2>\n\n\n\n<p>This is one of the most important differences between enterprise AI search platforms.<\/p>\n\n\n\n<p>Suppose two employees ask:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>&#8220;Show me the documents about the acquisition.&#8221;<\/p>\n<\/blockquote>\n\n\n\n<p>One employee works on the deal. The other does not.<\/p>\n\n\n\n<p>They should not receive the same results simply because the search system has indexed the same documents.<\/p>\n\n\n\n<p>A secure retrieval flow looks roughly like this:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>User identity\n     |\n     v\nSource permissions\n     |\n     v\nRelevant retrieval\n     |\n     v\nPermission filtering\n     |\n     v\nAnswer generation\n     |\n     v\nCited response<\/code><\/pre>\n\n\n\n<p>The implementation differs between platforms.<\/p>\n\n\n\n<p>Glean says its connectors inherit and enforce source-system permissions, including permission updates reflected in search results.<\/p>\n\n\n\n<p>Dashworks also advertises document-level access control and instant access-control updates on its Business plan. <\/p>\n\n\n\n<p>Vectara takes a different approach for fine-grained access. Its documentation describes attaching access metadata to documents and applying filters at query time. That means the application integrating Vectara has responsibility for supplying the appropriate authorization metadata and filters. <\/p>\n\n\n\n<p>That distinction matters. &#8220;Permission-aware&#8221; is not one standardized feature. Buyers should understand where permissions originate, how they are synchronized, and when they are enforced during retrieval.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"answer-quality\">Answer Quality<\/h2>\n\n\n\n<p>A good enterprise AI search system needs more than a capable LLM.<\/p>\n\n\n\n<p>The retrieval layer determines what evidence reaches the model in the first place. Poor retrieval can produce an incorrect answer even when the underlying model is strong. <a href=\"https:\/\/www.tooljunction.io\/blog\/best-llm-observability-tools-in-2026\">LLM observability<\/a> can help teams inspect retrieval steps, latency, traces, and evaluation results after deployment.<\/p>\n\n\n\n<p>Look for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>relevant source retrieval<\/li>\n\n\n\n<li>grounded answers<\/li>\n\n\n\n<li>citations and source links<\/li>\n\n\n\n<li>freshness of indexed information<\/li>\n\n\n\n<li>handling of conflicting documents<\/li>\n\n\n\n<li>semantic and keyword retrieval<\/li>\n\n\n\n<li>model flexibility<\/li>\n\n\n\n<li>controls for unsupported answers<\/li>\n<\/ul>\n\n\n\n<p>Glean combines search, organizational context, knowledge graphs and AI-generated answers. <\/p>\n\n\n\n<p>Onyx focuses on enterprise search and RAG while allowing organizations more control over models and deployment. <\/p>\n\n\n\n<p>Vectara is better understood as an enterprise RAG and retrieval platform than as a direct workplace-search clone. Its documentation focuses heavily on retrieval, ranking, filtering and grounded generation. <\/p>\n\n\n\n<p>That distinction is important when comparing products. A turnkey workplace assistant and a retrieval infrastructure platform can both appear under &#8220;enterprise AI search&#8221; while solving different problems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"deployment-data-residency\">Deployment &amp; Data Residency<\/h2>\n\n\n\n<p>Deployment requirements can eliminate a product before search quality is even considered.<\/p>\n\n\n\n<p>Some organizations are comfortable with a managed SaaS platform. Others need a private cloud, customer-controlled environment, self-hosting, or on-premise deployment because of regulatory or data-residency requirements.<\/p>\n\n\n\n<p>Onyx is particularly relevant for organizations that need self-hosted enterprise search and greater control over infrastructure and models. <\/p>\n\n\n\n<p>Elastic is another option for engineering-heavy teams that want to build and control their own search infrastructure. However, buyers should be careful with older references to <a href=\"https:\/\/www.elastic.co\/docs\/release-notes\/cloud-k8s\/breaking-changes\" target=\"_blank\" rel=\"noopener\">Elastic Enterprise Search<\/a>. Elastic currently says its standalone Enterprise Search, App Search, and Workplace Search products are in maintenance mode and recommends its actively developed Elastic Stack capabilities for new search experiences. <\/p>\n\n\n\n<p>Vectara offers another deployment model, with its current pricing page listing SaaS, VPC, and on-premise enterprise options.<\/p>\n\n\n\n<p>The practical question is not simply &#8220;Can it run in our cloud?&#8221; Ask who operates the software, who controls the data, and how much infrastructure responsibility remains with your team.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"pricing-per-seat\">Pricing Per Seat<\/h2>\n\n\n\n<p>Enterprise AI search pricing is difficult to compare because not every platform uses a simple per-seat model.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Platform<\/th><th>Pricing approach<\/th><th>Useful context<\/th><\/tr><\/thead><tbody><tr><td>Glean<\/td><td>Quote-based<\/td><td>Enterprise contract pricing is not presented as a simple public rate card<\/td><\/tr><tr><td>Dashworks<\/td><td>Per-seat<\/td><td>Team starts at $12 per seat\/month, with annual pricing shown at $10; Business starts at $15, or $12 annually<\/td><\/tr><tr><td>Onyx<\/td><td>Free\/community, cloud and Enterprise<\/td><td>Public cloud pricing and custom Enterprise options<\/td><\/tr><tr><td>Elastic<\/td><td>Usage\/resource based<\/td><td>Better viewed as search infrastructure than a per-seat workplace tool<\/td><\/tr><tr><td>Vectara<\/td><td>Enterprise deployment pricing<\/td><td>Current published starting points include $100K\/year SaaS, $250K\/year VPC and $500K\/year on-premise<\/td><\/tr><tr><td>Coveo<\/td><td>Enterprise quote<\/td><td>Pricing depends on the deployment and use case<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Dashworks publishes its current seat-based plans publicly. Vectara also publishes enterprise deployment starting points rather than a conventional workplace-search seat price. <\/p>\n\n\n\n<p>Do not compare these numbers as if they represent the same purchasing model. Implementation, infrastructure, connector requirements, usage, and engineering effort can materially change total cost.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"comparison-table\">Comparison Table<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Platform<\/th><th>Best fit<\/th><th>Permission approach<\/th><th>Deployment<\/th><th>Main trade-off<\/th><\/tr><\/thead><tbody><tr><td>Glean<\/td><td>Broad workplace AI search<\/td><td>Source permissions inherited and enforced<\/td><td>Managed enterprise<\/td><td>Less infrastructure control<\/td><\/tr><tr><td>Dashworks<\/td><td>Workplace search with real-time access<\/td><td>Document\/user access controls<\/td><td>Managed<\/td><td>Product approach differs from traditional indexed search<\/td><\/tr><tr><td>Onyx<\/td><td>Open-source enterprise search<\/td><td>Source permission inheritance<\/td><td>Cloud or self-hosted<\/td><td>More operational responsibility<\/td><\/tr><tr><td>Elastic<\/td><td>Custom search infrastructure<\/td><td>Document-level security and connector controls<\/td><td>Cloud or self-managed<\/td><td>Requires engineering investment<\/td><\/tr><tr><td>Vectara<\/td><td>Enterprise RAG and retrieval<\/td><td>Metadata and query-time filtering<\/td><td>SaaS, VPC, on-premise<\/td><td>More application responsibility for access controls<\/td><\/tr><tr><td>Coveo<\/td><td>Enterprise relevance and search experiences<\/td><td>Source permission handling<\/td><td>Managed enterprise<\/td><td>Broader relevance\/search use cases than workplace AI alone<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-to-choose-an-enterprise-ai-search-platform\">How to Choose an Enterprise AI Search Platform<\/h2>\n\n\n\n<p>Start with the problem, not the vendor shortlist.<\/p>\n\n\n\n<p>Choose Glean if you want a mature, managed workplace AI search experience with broad connector coverage and source-permission handling.<\/p>\n\n\n\n<p>Consider Dashworks if its real-time search approach and access-control model match how your organization wants to retrieve information.<\/p>\n\n\n\n<p>Onyx is worth evaluating when self-hosting, open source, model choice, or data control are important requirements.<\/p>\n\n\n\n<p>Elastic makes more sense when you have engineering resources and want to build a highly customized search and retrieval layer rather than buy a finished workplace assistant.<\/p>\n\n\n\n<p>Vectara is a better fit when the core requirement is enterprise RAG and retrieval infrastructure, especially when you need control over how retrieval and filtering are implemented. <\/p>\n\n\n\n<p>Coveo is worth considering for organizations where enterprise relevance extends beyond internal workplace search into service, commerce, or other search experiences.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"verdict\">Verdict<\/h2>\n\n\n\n<p>There is no single best enterprise AI search platform for every organization.<\/p>\n\n\n\n<p>Glean is the strongest benchmark for broad managed workplace search. Onyx stands out when self-hosting and open-source control matter. Dashworks offers a different approach to workplace retrieval. Elastic is better treated as customizable search infrastructure, while Vectara is particularly relevant to enterprise RAG. Coveo is a strong option when relevance and search extend across broader digital experiences.<\/p>\n\n\n\n<p>The most important buying question is not how many AI features a platform advertises.<\/p>\n\n\n\n<p>It is whether the system can connect to the right knowledge sources, retrieve information the user is actually authorized to see, produce grounded answers, and fit the organization&#8217;s deployment and cost requirements.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"fa-qs\">FAQs<\/h3>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-are-the-best-glean-alternatives\">What are the best Glean alternatives?<\/h3>\n\n\n\n<p>The best Glean alternative depends on the requirement. Onyx is particularly relevant for self-hosted and open-source deployments, Dashworks for workplace search, Elastic for engineering-led search infrastructure, Vectara for enterprise RAG, and Coveo for broader enterprise relevance and search experiences.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-does-permission-aware-search-work\">How does permission-aware search work?<\/h3>\n\n\n\n<p>Permission-aware search connects retrieval to a user&#8217;s existing access rights. The system should prevent information that the user cannot access in the original source from appearing in search results or generated answers. The exact implementation differs between platforms, so buyers should verify how permissions are synchronized and enforced.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-does-glean-cost\">What does Glean cost?<\/h3>\n\n\n\n<p>Glean does not present a simple public per-seat enterprise rate card. Current third-party comparison pages report various estimates, but those should not be treated as official pricing. Enterprise buyers should request a current quote and verify seat requirements, implementation costs, and contract terms rather than relying on an old published estimate. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"can-we-self-host-an-enterprise-ai-search-platform\">Can we self-host an enterprise AI search platform?<\/h3>\n\n\n\n<p>Yes, but the options differ substantially. Onyx supports self-hosted enterprise search, while Elastic provides search infrastructure that organizations can operate themselves. Vectara also publishes an on-premise deployment option. A managed platform running inside a customer&#8217;s cloud environment should not automatically be treated as equivalent to true self-hosting. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Enterprise AI search is no longer just about putting a chatbot over company documents.
