Claude for Enterprise

Pros

• Governance goes beyond the Team plan, with SCIM, audit logs, a Compliance API, custom retention, customer-managed encryption keys, and US-only inference.
• Claude Code and Cowork are included, and PeerSpot reviewers report much faster product shipping and workflow building.
• Many integration options: Microsoft 365 apps, Chrome, Google Workspace, Slack and Drive connectors, and MCP custom connectors for internal systems.
• No model training on customer data by default, plus a HIPAA-ready option with a BAA for regulated industries.
• Can be bought through AWS Marketplace, which lets companies draw down an existing AWS commitment.

Cons

• Seat fees no longer include tokens, so all usage bills at full API rates and costs are hard to predict.
• PeerSpot reviewers name pricing, credit consumption and hitting token limits as their main frustrations.
• The 20-seat minimum and annual-only billing rule out small teams.
• Some users report occasional hallucinations or stalled responses on complex projects.
• Volume and committed-spend discounts are not published, so buyers have to negotiate.

Sierra

Pros

• Outcome-based billing means customers usually pay only for resolved conversations or other agreed results, not for each seat.
• Three build options cover both CX teams and engineers: the no-code Agent Studio, the code-first Agent SDK, and Ghostwriter for building agents from SOPs.
• One agent runs across chat, voice, SMS, WhatsApp, email and ChatGPT, keeping context between channels.
• Its list of compliance attestations is broad, covering SOC 2, ISO 27001, ISO 42001, HIPAA, PCI DSS and FedRAMP.
• It has a strong roster of enterprise customers, including SiriusXM, ADT, Rocket Mortgage and SoFi.

Cons

• There is no public pricing, and competitor estimates put annual contracts at about $150,000 or more.
• There is no self-serve or trial tier, so small teams cannot try it on their own.
• Implementation is largely vendor-led, which can make customers depend on Sierra's team for changes.
• There are few public reviews (7 on Gartner Peer Insights) to verify claims against.
• Some reviewers say voice quality still falls short of human level, and that complex telephony setups depend on how far the integration goes.
