A SiteHawk Alternative: Sphera SDS Management vs SDSentry

Short answer: SiteHawk, the SDS and chemical data management company founded in 1993 in Smyrna, Tennessee, was acquired by Sphera, announced May 6, 2019 (per Sphera’s own press release). Today Sphera sells SDS management as part of its enterprise Chemical Management software, by demo, with no published price. SDSentry is a published-price alternative for small US employers: $24 per location per month, no SDS cap, and the OSHA HazCom paperwork in one place.

Free, no signup: the OSHA HazCom self-audit at sdsentry.0xpi.com/hazcom-self-audit.html scores your Hazard Communication program against 29 CFR 1910.1200 in about two minutes and names the specific gaps.

What happened to SiteHawk (checked October 11, 2026)

• Acquired by Sphera. Sphera’s press release of May 6, 2019 announces the acquisition of SiteHawk, “a leading software and services provider for Safety Data Sheets (SDS) and chemical data management solutions”, founded in 1993 and based in Smyrna, Tennessee. Terms were not disclosed.
• The old website. When we tried sitehawk.com on October 11, 2026 it did not load a website, so the current offer is the one on sphera.com.

What Sphera’s SDS management offers today

From Sphera’s own pages on October 11, 2026:

• Safety Data Sheet Management — universal access to SDSs, tracking of chemical arrivals and departures, storage, usage and quantities, reports for employees, suppliers, customers and regulators, configurable material-approval workflows, and integration through reports, Excel or APIs. Sphera says it keeps your SDSs up to date.
• Chemical Management Software — Sphera’s experts index over 300 unique points on your supplier SDSs, and SDSs are updated at least every 24 months, with Sphera’s experts calling suppliers. It is “designed from the ground up for enterprise-wide implementations on a global scale”, with modules for chemical inventory, chemical risk assessment and document storage, alongside Sphera’s SDS authoring, product compliance and wider EHS software.

How Sphera SDS management is priced

The SDS Management page leads to “Request a demo”: fill out the form and Sphera gets back to you. We found no published price on sphera.com on October 11, 2026, and we do not estimate one. If you are getting a quote:

• Is the price per location, per user, per SDS, or a platform fee? What happens when you add a site or a product?
• Which modules are in the quote — SDS management only, or labels, inventory, training and reporting too?
• Are there implementation, onboarding or library-build fees on top of the subscription?
• What is the contract term, does it auto-renew, and what is the notice period to cancel?
• Can frontline employees reach the sheets without their own login, and offline?

What SDSentry costs and covers

SDSentry publishes its price on its home page: $24 per location per month or $199 per location per year — an OSHA-deadline price (regularly $49) that stays locked for as long as you subscribe if you start by November 20, 2026. Unlimited users and no SDS cap at each location. The 7-day free trial needs a card ($0 today) and converts to paid unless you cancel.

It covers the US Hazard Communication paperwork a small employer is asked for: multi-source SDS lookup plus your own uploads, a per-location chemical inventory, GHS secondary-container labels, workplace posters, the written HazCom program, per-product training with e-signatures, OSHA 300 recordkeeping, EPCRA Tier II export, and a no-login Shared SDS Binder that works offline.

When Sphera is the better choice

If you are a manufacturer or multi-site enterprise that needs expert-indexed SDS data, material approval before chemicals arrive on site, reporting to customers and regulators, API integration with other systems, SDS authoring or product compliance across many countries, Sphera is built for that and SDSentry is not. SDSentry is a young, single-developer product for small US employers that need the OSHA HazCom essentials at a published price.
