Parloa vs Sierra
A side-by-side comparison of Parloa and Sierra on what each one charges, what it meters, and which plan every capability actually sits on.
Capability by capability
Nothing we track differs between them.
Channels
| Capability | Parloa | Sierra |
|---|---|---|
| Not published | IncludedNo plans are published, so plan gating cannot be assessed. | |
| Live chat | IncludedPublished as a first-class channel alongside voice: "Deploy to voice, chat, messaging, and more", with chat, messaging, phone, click-to-call and multimodal listed on the platform architecture diagram. | IncludedNo plans are published, so plan gating cannot be assessed. |
| Voice | IncludedThe primary channel and the origin of the product, voice-first since 2018. Calls arrive over SIP into the customer's CCaaS or VOIP infrastructure, and Parloa runs its own carrier-grade telephony underneath rather than a third party's. | IncludedNo plans are published, so plan gating cannot be assessed. |
| Not published | IncludedNo plans are published, so plan gating cannot be assessed. |
AI resolution
| Capability | Parloa | Sierra |
|---|---|---|
| Autonomous resolution agent | IncludedPublished outcomes include a global furniture brand where "AI agents handle 100% of calls", GESOBAU at 66% of qualified calls resolved automatically, and MEG at 42% of customer calls automated. No accuracy SLA accompanies any of them. | IncludedThe whole product. Sierra bills only on outcomes such as "a resolved support conversation", which presupposes autonomous resolution. |
| Action-taking (API calls) | IncludedAuthenticated connectors to Salesforce, ServiceNow, Zendesk and Microsoft Dynamics 365, pre-configured Knowledge, Routing and Custom Skills attached directly to an agent, REST APIs for custom services, and MCP Skills released in June 2026. | Included"Enable your agent to take action to assist customers by securely connecting it with any internal or external system", including systems of record from order management to CRM. |
| Handoff to human | IncludedSummaries carrying intent, actions attempted, escalation reason and accessed account context are pushed into CCaaS or CRM before the human picks up. The SAP Service Cloud integration passes conversational context into the Agent Desktop at handoff. | IncludedEscalation exists and is usually not billed: "if a case needs to be escalated, in most cases, there's no charge". The exceptions are unpublished. |
| Guardrails & citations | IncludedPer-agent safety controls that "block harmful content, detect jailbreak attempts, and restrict off-topic conversations", topic enforcement, social-engineering and PII-extraction detection analysing full conversation history each turn, and LLM Guardrails shipped July 2026. Checks run in parallel with the response "for no added latency". | IncludedGuardrails are published as "supervisory layers to reduce hallucinations, ensure security, and prevent abuse", and PII is "automatically encrypted and masked". Citation behaviour is not addressed anywhere, so half of this attribute is Unknown. |
| Multilingual AI | IncludedGenuinely central to the product and genuinely inconsistent in the numbers. Published counts run 130+, 140+ and 100+ on different pages, with Real-Time Translation quoted separately at 30+. The one auditable deployment figure is BER Airport running four languages. | IncludedSierra publishes "voice, chat, email, and WhatsApp in 59 languages", available 24/7/365. |
AI voice
| Capability | Parloa | Sierra |
|---|---|---|
| Voice agent | IncludedThe product. Parloa calls it an AI Agent Management Platform, managing the lifecycle of AI agents across Design, Test, Scale and Optimize for enterprise contact centres. | IncludedVoice is listed as a first-class agent channel alongside chat, email and WhatsApp. No per-minute rate or telephony passthrough is published. |
| IVR replacement | IncludedPublished as a named use case with a customer story titled "1.5 million interactions handled by AI agents annually: The telecommunications IVR replacement playbook", and routing is one of the pre-built Skills shipped with the platform. | Not published |
| Call summarization | IncludedAI-generated summaries "capture customer intent, actions taken, and conversation outcomes", derived from transcript data in the Conversation Store and retrievable through the Transcripts API. | Not published |
Reporting
| Capability | Parloa | Sierra |
|---|---|---|
| Raw data export | Included"Export data to in-house dashboards or business intelligence tools for deep analysis", with a Data Hub and Sharing component and a Conversation Store in the published architecture. No format, destination or connector is named, and Transcripts API access is enabled per organisation on request. | Not published |
Enterprise
| Capability | Parloa | Sierra |
|---|---|---|
| SAML SSO | IncludedListed in the Trust Center under Product Security as SSO Support. The protocol, the identity providers and any plan gate are not stated, and there are no plans to gate it against. | Not publishedNot addressed on the trust and reliability page or any product page. |
| Role-based access control | Included"Granular access control with role-based permissions" on the security page, listed again in the Trust Center under Product Security as Role-Based Access Control alongside Multi-Factor Authentication. | Not published |
| Audit logs | Included"Audit-ready architecture with traceable logs" and "Every conversation is logged, searchable, and fully auditable", with version control over agent changes. Whether the trail can be exported is not published. | Not publishedAI audit logging is not addressed on the trust and reliability page or any product page. |
| Sandbox environment | IncludedStaging and production environments with promotion between them, plus simulation against thousands of synthetic and historical conversations, LLM-based and rule-based scoring, and regression testing before release. | Not published |
| HIPAA / BAA | Not publishedHIPAA appears in the Trust Center as a certificate entry and a report, and the Knowledge Hub says the platform "aligns with HIPAA". No page offers or mentions a business associate agreement, and healthcare is a named industry with live deployments. | IncludedNot assessable; no plans are published. |
| SOC 2 | IncludedNone stated. No plans are published, so plan gating cannot be assessed either way. | IncludedNot assessable; no plans are published. |
| ISO 27001 | IncludedNone stated. No plans are published. | IncludedNot assessable; no plans are published. |
| GDPR | IncludedNone stated. No plans are published. | IncludedNot assessable; no plans are published. |
| Data residency | Included"Data residency controls and regional hosting options aligned with local jurisdictional requirements", on Azure regions across North America, Europe and Asia-Pacific. No named region, no EU-only inference guarantee and no statement of which regions come with which contract. | Not publishedNo region list appears on the trust and reliability page or anywhere else on sierra.ai. PCI cardholder data runs on "dedicated PCI certified infrastructure" segregated from the core platform, which is infrastructure segregation rather than a residency or VPC option. |
Developer
| Capability | Parloa | Sierra |
|---|---|---|
| REST API | IncludedREST APIs for custom services and external data sources, plus the Transcripts API for conversation data. The AMP documentation at docs.amp.parloa.com is behind a login and access is granted by a Parloa representative, so no public API reference exists to check rate limits or schemas against. | Not publishedNo public API reference is published on sierra.ai. The Agent SDK page describes extensibility without documenting an API. |
| SDKs | Not published | IncludedThe Agent SDK is a published product surface, described as extensible so customers can write and connect their own integrations. No public API reference is published. |
