What is Envoy?
Envoy turned the roster it already had into a physical-security product, and is now hardening it.
The August 7 release moved Envoy into threat monitoring: a Threat Dashboard tracking verified global and local risks, employee home addresses synced from HRIS, and per-individual monitoring for executives and other VIPs. The releases since have been operational hardening — location-scoped blocklists so site teams can act without touching the company-wide list, and an audit log covering published changes to the workplace map. Around that, steady platform work continues across Visitors, Workplace, Screens, and the Developer API.
What is Sling?
A twice-monthly scheduling explainer mill; the product itself never appears.
Sling publishes on the 1st and 15th of each month, alternating between shift-scheduling concepts (shift differentials, the DuPont rotation, schedule types) and general people-management listicles. The newest entry is a 47-item list of employee improvement areas. Across the full visible window, going back to March, not one entry describes a change to the scheduling product.
Envoy vs Sling: editorial side-by-side
Envoy
6.3HR
Envoy turned the roster it already had into a physical-security product, and is now hardening it.
◆ Current state
The August 7 release moved Envoy into threat monitoring: a Threat Dashboard tracking verified global and local risks, employee home addresses synced from HRIS, and per-individual monitoring for executives and other VIPs. The releases since have been operational hardening — location-scoped blocklists so site teams can act without touching the company-wide list, and an audit log covering published changes to the workplace map. Around that, steady platform work continues across Visitors, Workplace, Screens, and the Developer API.
◆ Where it's heading
Envoy is converting data it already holds — locations, employee directory, desks, visitor records — into products that sit beside the originals rather than requiring new collection. Response is the clearest instance: it works out of the box for every existing location and deepens when the HRIS directory sync shipped in July is switched on. The two releases that followed suggest the near-term concern is making these surfaces auditable and delegable enough for multi-site administration, where a single global list or an untracked map edit becomes a real operational problem.
◆ Prediction
Response most likely gains administrative depth next — alerting rules, roles, and reporting — following the same scope-and-audit pattern just applied to blocklists and the workplace map. The entries give no indication of how Response is packaged or priced against the existing plans.
Sling
5.0HR
A twice-monthly scheduling explainer mill; the product itself never appears.
◆ Current state
Sling publishes on the 1st and 15th of each month, alternating between shift-scheduling concepts (shift differentials, the DuPont rotation, schedule types) and general people-management listicles. The newest entry is a 47-item list of employee improvement areas. Across the full visible window, going back to March, not one entry describes a change to the scheduling product.
◆ Where it's heading
The topic mix is drifting away from scheduling mechanics toward broad management and restaurant-operations content, which widens search reach but moves further from what the product does. The fixed twice-monthly rhythm and templated meta-description ledes mark this as a content calendar running independently of engineering. This feed will not show product movement.
◆ Prediction
Expect the next entries on or near the 1st and 15th, continuing the alternation between scheduling terminology and restaurant-management listicles. No sparks will come from this source while it carries no release notes.
