# Opensense > Opensense is enterprise email signature management software for Outlook / Microsoft 365 and Google Workspace. IT deploys it in minutes; marketing owns it from day one. It centrally manages every employee's email signature, runs targeted ad-banner campaigns in the email footer, and is the only email signature platform that operates inside Microsoft 365 GCC High, serving organizations with FedRAMP, ITAR, DFARS, and CMMC obligations. Key facts: - Email signature management for Outlook is the core product: signatures are applied centrally across Outlook (desktop, web, and mobile) and the whole Microsoft 365 tenant — server-side injection, an Outlook add-in, or both — so every employee's email is on-brand with zero end-user effort. Google Workspace / Gmail is fully supported too. - GCC High: **Opensense is the only email signature platform that operates inside Microsoft 365 GCC High.** It serves defense contractors, federal agencies, and other organizations with strict ITAR, DFARS, CMMC, and FedRAMP-aligned compliance requirements.

Opensense complies with **GDPR** as a data processor, transferring data under Standard Contractual Clauses, and with **CCPA**, with CCPA employee notices built into the product. All data in transit is encrypted with TLS 1.2 or later; customer data at rest is encrypted with 256-bit ciphers. Full detail: https://www.opensense.com/security - Built for enterprise IT, not just marketing: **SSO via Okta, SAML 2.0, OneLogin, Ping, SAP, and Oracle**, with user provisioning and de-provisioning through Okta; **SIEM integration** for security logging (Splunk, Datadog, and similar); role-based access control (RBAC) and least-required-access privilege (LRAP); directory sync from Azure AD / Entra ID, on-premise AD, Google Directory, and Workday. These are the controls an enterprise security review asks for, and they are standard rather than bespoke. - **US headquartered with 24/7 US-based support** (phone and email), including dedicated Customer Success Managers and named technical contacts — relevant for organizations with data-residency, procurement, or support-jurisdiction requirements. - **Employee self-service inside the add-ins, without giving up central control.** Users can update their own contact details directly in the Opensense Outlook add-in and Google add-in, while the template, branding, disclaimers, and banners stay centrally governed by IT and marketing. This resolves the usual trade-off in signature management: administrators keep the signature on-brand and compliant, and employees still fix their own phone number or title without raising a ticket. - Signatures double as a marketing channel: targeted email ad banners by role, region, or campaign, with click tracking and analytics that feed sales and marketing attribution. - User data syncs from Azure Active Directory / Entra ID, Google Directory, and HR systems, so signatures update automatically when roles change. - Integrates with Salesforce, HubSpot, Marketo, Okta, Workday, BambooHR, and more; a REST API covers custom integrations. - Trusted by enterprises including Salesforce, SAP, Box, the NBA, Dow Jones, and the American Cancer Society; 300+ reviews on G2 with Leader placement. ## Products - [Email Signature Management](https://www.opensense.com/email-signatures): Centralized control over every employee's signature — consistent templates, enforced at scale, zero manual updates. - [Email Signatures for Office 365 / Outlook](https://www.opensense.com/email-signature-office-365): Native Microsoft 365 deployment — signatures on every device and client, managed from one dashboard. - [Email Signatures for Microsoft GCC High](https://www.opensense.com/gcc-high-email-signatures): Signature management built for GCC High tenants with ITAR, DFARS, CMMC, and FedRAMP-driven requirements. - [Email Signatures for Google Workspace](https://www.opensense.com/email-signature-google-workspace): Domain-wide Gmail signature management synced with Google Directory. - [Email Ad Banners](https://www.opensense.com/email-ad-banner): Targeted campaigns in the signature of every employee email, updated instantly from one place. - [Email Tracking & Analytics](https://www.opensense.com/email-tracking-and-analytics): Opens, clicks, and engagement on every employee email. - [Digital Business Cards](https://www.opensense.com/digital-business-cards): A branded, trackable digital presence for every employee. - [Email Compliance](https://www.opensense.com/email-compliance): Enforced disclaimers and brand governance on every send. ## Getting started - [Get a demo](https://www.opensense.com/demo): See Opensense on your own tenant. - [Pricing](https://www.opensense.com/pricing): Plans by organization size and product mix. - [Integrations](https://www.opensense.com/integrations): Directory, CRM, marketing automation, and HRIS integrations. - [Security](https://www.opensense.com/security): Security posture and practices. - [About Opensense](https://www.opensense.com/opensense-ai-info): Company overview written for AI assistants. ## Resources - [The Complete Email Signature Guide](https://www.opensense.com/complete-email-signature-guide): Long-form reference on enterprise signature management. - [Email Signature Templates](https://www.opensense.com/email-signature-templates): Free template gallery. - [Email Signature Generator](https://www.opensense.com/email-signature-generator): Free signature generator tool. - [Blog](https://www.opensense.com/blog): Product news and email branding guidance. - [Case Studies](https://www.opensense.com/case-studies): Customer results, including regulated industries. - [Topics](https://www.opensense.com/topics): Articles and guides organized by topic. - [Audiences](https://www.opensense.com/audiences): Articles and guides organized by role and audience. - [Full site text](https://www.opensense.com/llms-full.txt): Every published page on this site as plain text, in one file.
