Browser-Layer Identity Security: Push Security vs. Nudge Security vs. Grip Security

All three vendors sell a broader platform than the single capability compared here. This table is scoped to browser-layer identity risk detection specifically, not each vendor's full feature set.

The single biggest difference between these three products is whether the browser extension is the detection engine or an optional accessory bolted onto a different core signal.

Push Security has no agentless mode for its core identity-attack detections. The browser extension is deployed enterprise-wide and is itself the sensor: it watches login flows, page content, and session behavior directly inside the browser, in real time, as an employee actually types a password, clicks through a consent screen, or lands on a cloned login page. That in-browser vantage point is why Push can detect adversary-in-the-middle (AiTM) phishing toolkits and malicious copy-paste attacks (the ClickFix pattern, where a victim is talked into pasting attacker-supplied text into a Run dialog or terminal) as they happen, rather than reconstructing them afterward from a log. In 2026 Push added an AI-native detection engine that generates and tests new detection hypotheses against live browser telemetry on an ongoing basis, and separately added detection for malicious browser extensions themselves, both building on the same always-on, in-browser sensor rather than a new data source.

Nudge Security and Grip Security both start from the opposite direction. Their base product connects to an identity provider (Google Workspace or Microsoft 365) and, in Grip's case, corporate email flows and SSO/IdP records, and builds an inventory of SaaS accounts and OAuth grants from that metadata, with no browser footprint at all. That agentless model is fast to stand up but structurally cannot see an event that never touches the monitored IdP or generates a recognizable vendor email, which is exactly the shadow SaaS sign-up and personal-account password-reuse pattern this whole comparison is about. Both vendors address that gap the same way: an optional browser extension layered on top. Nudge Security's extension adds detection of weak and reused passwords, credential sharing, MFA or SSO bypass attempts, and unauthorized password manager use, plus browser-based discovery of AI agents built on platforms without public APIs. Grip Security's Grip Extend adds a comparable set (unmanaged app sign-in detection, missing MFA per app, weak/reused passwords, shared-account detection) and layers in what Grip calls ITDR 2.0: tracking session behavior after a token is issued, looking for token anomalies, suspicious page activity, and signs of impersonation, addressing the specific gap where an IdP's visibility ends the moment a session token is handed off and a browser extension is one of the few vantage points left to watch what happens to it next.

The practical consequence: if browser-native identity attacks (phishing kits that beat MFA, stolen session tokens, malicious extensions) are the primary risk you're trying to close, Push's architecture is purpose-built for that from the ground up. If the primary risk is inventory and governance of shadow SaaS and OAuth sprawl, with identity-attack detection as a secondary layer added later, Nudge's or Grip's agentless-first model gets you value faster, with the browser extension as a deliberate second phase rather than a day-one requirement.

Push Security requires committing to a browser extension rollout across the managed device fleet from the start, since that is the only way its core detections function. In practice this means pushing the extension through Chrome Enterprise, Intune, or equivalent browser-management policy to the population you want covered, and treating unmanaged or BYOD devices outside that policy as a known gap rather than something the product will quietly pick up later.

Nudge Security's base tier connects to Google Workspace or Microsoft 365 and the vendor states this integration takes under five minutes to produce an initial inventory, with no endpoint or browser rollout required. Adding the browser extension is a separate, later step, typically piloted with a subset of the workforce before wider rollout.

Grip Security follows the same two-phase pattern: the initial email/SSO connection requires no agent or browser change, and Grip Extend is deployed afterward via Group Policy Object to Chrome and Edge, as an explicit add-on decision rather than part of the base setup.

Push Security's value does not depend on deep SaaS or IdP API integration, since its core signal comes from the browser itself; it is designed to sit alongside an existing identity provider and forward detections into a SOC's existing tooling rather than replacing IdP-level visibility.

Nudge Security integrates primarily with Microsoft 365 and Google Workspace as the identity and email backbone for its core discovery, and separately supports browser-based discovery of AI agents built on platforms such as Retool, Zapier, and OpenAI Workflows once the extension is deployed.

Grip Security integrates with corporate email and SSO/IdP systems as its baseline signal, with Grip Extend as an additional, optional browser data source layered on top, and is also listed as a connector in third-party identity governance ecosystems such as SailPoint's.

For any of the three, verify during a proof of concept exactly which alerting and SIEM/SOAR forwarding paths are documented for your own stack; none of the three publish an exhaustive, independently verified integration catalog specific to the browser-layer identity capability covered in this comparison.

Push Security carries the highest day-one operational commitment of the three, because there is no lightweight agentless phase to defer the decision: rolling out and maintaining the browser extension across the fleet, plus tuning detections and triaging real-time alerts, becomes part of the job from the start. In exchange, it is the only one of the three built to catch a phishing kit or a stolen session token while the attack is actually in progress rather than after the fact.

Nudge Security and Grip Security both minimize initial effort with their agentless base tier, an inventory can be running within minutes of connecting an IdP. Effort rises specifically when the browser extension layer is added: a pilot rollout, ongoing extension policy management, and triage of the new credential-hygiene and (for Grip) session-anomaly alerts that layer introduces. Both vendors treat that as a deliberate second phase, so a team can defer it until the base inventory shows enough shadow SaaS or OAuth risk to justify the additional deployment.

Nudge Security is the only vendor of the three with pricing published directly on its own site: an Essential plan at $750 per month for organizations up to 150 users, and a Growth plan at $5 per user per month for organizations between 150 and 1,500 users, both billed annually, with a custom Enterprise plan above that. Whether the browser extension layer carries its own separate charge or is included in these tiers is not stated on the public pricing page; confirm that directly with sales before budgeting.

Push Security does not publish per-seat or tiered pricing on its own site as of this writing. Get a written, scoped quote based on workforce size and which of its four stated use cases (identity/shadow IT hardening, AI visibility and control, detection and response, DLP/insider threat investigation) you intend to deploy, since pricing is likely to vary with scope even if it is not published.

Grip Security also does not publish per-seat pricing. Its browser extension, Grip Extend, is confirmed to carry an additional fee on top of the base platform, billed either annually or monthly, and the platform overall is sold through custom quotes and, in at least one observed case, an AWS Marketplace private offer. Do not rely on third-party marketplace listings that estimate a price range for either vendor; they are not vendor-confirmed.

Push Security strengths: the only one of the three where browser-native identity attacks, AiTM phishing kits that beat MFA, cloned login pages, malicious copy-paste (ClickFix) attacks, and malicious browser extensions, are caught in real time by the core product rather than by an optional add-on; a 2026 AI-native detection engine that the vendor states is materially increasing how fast new attack techniques get covered. Push Security limits: no agentless option, so an organization unwilling or unable to mandate a browser extension across its workforce (heavy BYOD, no MDM, strong employee pushback on endpoint monitoring) cannot get its core value at all; no public pricing to anchor an early budget conversation.

Nudge Security strengths: genuinely fast, agentless setup for the base SaaS/OAuth inventory; the only vendor here with published, predictable pricing, which materially eases budget approval for a lean security team evaluating this category for the first time; an extension layer that specifically targets credential hygiene (weak passwords, reuse, sharing, MFA/SSO bypass) once added. Nudge Security limits: the base agentless model is blind to identity events that never touch the monitored IdP or generate a recognizable vendor email, meaning a personal-email shadow SaaS sign-up or an in-browser phishing session can be missed entirely until and unless the optional extension is deployed.

Grip Security strengths: a session-token-specific detection layer (ITDR 2.0 via Grip Extend) that directly targets the gap where an IdP's visibility ends once a token is issued, which neither of the other two vendors names as a discrete capability in the same way; a genuinely agentless first pass for teams not ready to add a browser extension yet. Grip Security limits: the identity-attack-specific detections (unmanaged sign-ins, session anomalies, shared-account detection) all sit behind the paid Grip Extend add-on rather than the base platform, and no public pricing exists for either the base platform or the add-on to plan around.

Push Security tends to fit organizations whose top identity risk is the browser-based attack itself, phishing kits that defeat MFA, session token theft, malicious extensions, and that have both the mandate and the device management (MDM, Chrome Enterprise, Intune) to roll out a browser extension across the workforce from day one. It fits less well for a team that wants to start with a lightweight, agentless first phase.

Nudge Security tends to fit lean security teams, often a handful of people, on Google Workspace or Microsoft 365, that want the fastest possible agentless inventory of shadow SaaS and OAuth risk with predictable, budget-friendly pricing, adding the credential-hygiene extension only once that base inventory justifies the next investment.

Grip Security tends to fit mid-size to large organizations that already run, or are building, a broader SaaS-identity governance program and want post-login session-token monitoring specifically layered onto that program once it is established, rather than as a first purchase.

None of the three is a universal winner. The right choice depends on whether your organization can mandate a browser extension immediately (Push), wants to defer that decision behind a fast agentless inventory (Nudge or Grip), and how much of your SaaS estate is already behind single sign-on versus scattered across personal-account shadow sign-ups the IdP will never see.

Hold off on all three, at least for now, if any of the following apply.

Your SaaS estate is small and already almost entirely behind single sign-on, with a functioning SSPM tool already covering OAuth-grant governance for the applications you know about. In that case, a periodic manual audit of connected apps, using the procedure in our SaaS OAuth token sprawl audit guide, plus your existing SSPM coverage, may be sufficient until shadow SaaS sign-ups or personal-account credential reuse actually show up as a measurable problem.

Your workforce is heavily BYOD with no practical way to deploy or enforce a browser extension. Push's core detections require it outright, and the identity-attack-specific layers of Nudge and Grip both live behind their own optional extensions; without extension deployment, all three collapse toward the same blind spots that IdP logs already have.

Your identity architecture is not yet settled, for example mid-merger with multiple identity providers still active, or no consolidated IdP at all. All three tools depend on IdP or SSO signal quality for at least part of their value; consolidating identity first, a prerequisite covered in our non-human identity security guide for the machine-identity side of the same problem, will make any of the three more effective once purchased.

Your actual gap is OAuth consent phishing response rather than ongoing browser-layer visibility, for example you already know you need a runbook for revoking a stolen OAuth token after a ConsentFix- or EvilTokens-style attack. That is a narrower, more urgent problem covered directly in our OAuth consent phishing detection and response guide, and is worth solving on its own before evaluating a standing browser-identity platform.

There is no plan or headcount to act on what any of these tools surfaces. A tool that flags reused passwords, risky OAuth grants, or session anomalies is only useful if someone reviews the alerts, follows up with the affected user, and revokes or remediates. Buying any of the three without that follow-through capacity produces a dashboard nobody acts on.

Run any shortlist candidate against these checks before committing budget. None of the three vendors' detection-coverage claims in this comparison have been verified by independent third-party testing, so treat every vendor statement as a hypothesis for the PoC to confirm, not a settled fact.
