Sentry Interactive

Sentry Interactive adds mobile credentials to compatible physical access control systems, allowing organizations to offer phone-based door entry while keeping existing reader hardware. A phone can unlock through an NFC tap or QR code, and iOS or Android widgets provide remote door access. Users can share time-sensitive digital keys, while administrators set time, geofence, and IP restrictions. Credentials for tenants, employees, and visitors can be managed from a desktop, tablet, or smartphone. Sentry says its service works with more than 20 access control systems and can be embedded in third-party building or management apps. Its SDK can also add mobile credentials to an organization’s own app. Smart Access Tiles are passive NFC units placed near doors; they need no power or cabling and link to the cloud through QR code. Sentry describes its security approach as using asymmetric cryptography and Zero Trust, with audit logging and privacy regulation compliance. Pricing is available on request. Compatibility depends on supported systems and readers.

Sentry provides a mobile credential layer for compatible physical access systems, with multiple entry methods and administrative controls. Organizations should confirm their system and readers are supported before considering deployment.

Sentry Interactive is aimed at access-control manufacturers, software developers, security integrators, and IT and cybersecurity MSPs. It may suit organizations seeking to add mobile credentials to compatible access systems.

Overview

Sentry Interactive adds phone-based credentials to physical access systems, best suited to organizations and technology partners seeking to extend an existing access setup. Its appeal is mobile entry without replacing compatible door hardware; the key caveat is that both the access system and readers must be supported.

Key features

Mobile entry with adjustable rules. Users can unlock with an NFC tap or QR scan, use iOS or Android widgets for remote door access, and share time-sensitive digital keys. Administrators can apply time, geofence, and IP restrictions. That mix is useful for managing different groups and temporary access, but its value depends on the installed system’s compatibility.

Reuse hardware or add passive tiles. A smartphone can serve as the NFC reader, allowing compatible existing readers and access hardware to stay in place. Sentry’s Smart Access Tiles provide another option: passive tiles placed beside doors that need no power, batteries, or cabling and connect to the cloud through QR code. These approaches can reduce hardware changes, but they do not eliminate compatibility checks.

Integration and administration. Sentry says its credentials work with more than 20 physical access-control systems and can be embedded in third-party building and management apps. Its SDK lets developers add credentials to an organization’s own app, while an open enrollment service supports mass enrollment of asymmetric mobile and physical credentials, including PKOC, when embedded in a compatible system. Credentials for tenants, employees, and visitors can be managed from a desktop, tablet, or smartphone. This breadth is most relevant to integrators, developers, and operators with an existing system to connect.

Security and rollout. The company describes its credentials as using asymmetric cryptography and Zero Trust, aligning with NIST Cybersecurity Framework 2.0, and supporting audit logs and privacy-regulation compliance. It also says cloud access data is protected with military-grade encryption and that credentials can be deployed remotely, with rollout advertised within days. These are maker-stated security and deployment claims, not a substitute for confirming how the product fits an organization’s own requirements.

Pricing

Sentry is paid software with custom pricing. Organizations should request a quote for their system and deployment needs; no published plan tiers, seat caps, quotas, trial length, or renewal terms are provided here. That makes it difficult to compare total cost before discussing integration, but also means prospective buyers can seek pricing around their specific setup.

Platforms

Sentry supports Android, iOS, web, and API access. Mobile apps serve credential holders, while desktop and tablet access lets administrators manage credentials across tenant, employee, and visitor groups.

Who it's for

Sentry is aimed at access-control OEMs, software developers, security integrators, and IT and cybersecurity managed service providers, as well as organizations operating compatible physical access systems. It is a stronger fit for teams that want credentials incorporated into an existing access environment or app than for buyers seeking a standalone product independent of their current readers. The company says a team member will respond within 24 hours and offer a system audit for integration.

Pros and cons

• Pros: Mobile NFC and QR entry, remote access widgets, temporary key sharing, and credential restrictions cover several common access needs.
• Pros: Keeping compatible hardware in place, plus passive Smart Access Tiles, can avoid reader replacement or powered door-side equipment.
• Pros: SDK, third-party app embedding, and broad enrollment support give developers and integrators options for fitting credentials into existing systems.
• Cons: Supported access systems and readers are a hard dependency, so organizations must verify compatibility before planning a rollout.
• Cons: Custom pricing and the absence of public plan terms make budget and package comparisons harder before contacting the company.

Alternatives

For gym operators comparing access products, the Gym Access Control Software list is a useful starting point.

Seam is worth considering when a published entry plan matters: its Unit Access plan is $5 a month and includes five actions per device per day, priority email support, full API access, webhooks, and supported brands; it also has a free plan and free trial.

Beckon Access may suit buyers looking for club-management functions alongside access, with a €99 a month monthly add-on covering memberships, contracts, user accounting, SEPA direct debit, and online payments; it has a free plan but no free trial.

Gantner Fitness Check-In and Access Control is another paid option for readers comparing fitness check-in and access-control software.

re:membr Access Control is another paid access-control option, with Android, iOS, and web platforms.

Swiftlane may appeal to buyers who want a free plan or trial and a defined video-clip package: its Motion Detection Video Clips plan costs $30 a month per intercom device, with up to 300 daily clips, 15 seconds per clip, and 30-day cloud retention.

Gymetic is a paid alternative with custom pricing for readers seeking a demo-based quote.

Brivo Security Suite is another paid option; its Standard plan includes one year of data retention and five Brivo Mobile Passes, with pricing through a reseller.

GymAxess may be a fit for buyers comparing door- or location-license pricing, with listed monthly licenses of €10 per door and €50 per location.

Verdict

Choose Sentry Interactive if you need mobile credentials layered onto a compatible physical access system, particularly when retaining hardware or embedding access in an existing app matters. Its flexible entry methods, access rules, and integration options are compelling for operators and access-control partners. Look elsewhere if you need transparent upfront pricing or cannot confirm that your readers and system are supported.
