From detection to containment in seconds, not shifts.

SafeToOpen catches the phishing page or the malicious email. Your stack does the rest, on one confirm or with no analyst at all: the URL is blocked in your DNS filter, secure web gateway, endpoint protection and firewall, the user is signed out and asked to reset their password, the sender is blocked at the mail gateway, and the on-call is paged. The same tools you already pay for, wired to a verdict that arrives before the loss.

25+ connectors, no agents to install Confirm-to-run or fully automatic Dry-run, undo and audit trail Per-client scoping for MSPs

One incident. Every layer of your stack, at once.

A verdict from the browser or the inbox becomes a set of actions across the tools you already run. You decide which actions need a human and which run on their own.

01 · Detect

The page or email is judged as it appears

Browser Security scores the page the moment it loads; Email Security verifies the message in Outlook or Gmail. Zero-day threats included, no feed required.

0.3 s to verdict
02 · Triage

Context arrives with the alert

The incident carries the URL, the sender, the affected user and the evidence. An incident card lands in Slack or Teams; PagerDuty or Opsgenie pages the on-call if severity warrants it.

Slack · Teams · PagerDuty · Opsgenie
03 · Contain

One confirm, every tool

Block the URL organisation-wide and in your DNS filter, gateway, EDR and firewall list. Sign the user out and force a password change. Block the sender for the whole tenant. All in parallel.

Seconds, not tickets
04 · Close the loop

Ticket, audit and undo

The incident is pushed to ServiceNow or Jira and your SIEM. Every action records who ran it and what the vendor returned. Reversible actions can be rolled back from the console.

Where the actions land

Each connector uses the vendor’s documented API with the smallest permission set that does the job. Secrets are encrypted at rest and never leave your organisation’s configuration.

Network & web filtering

Block the URL or domain for every device behind the filter, whether or not it runs the extension.

  • Cisco Umbrella
  • Zscaler Internet Access
  • Netskope
  • Cloudflare Zero Trust

Firewalls via hosted blocklist

A per-organisation list your firewall pulls on a schedule, in the format it expects. Confirmed incidents, your threat feeds and your manual blocks, in one address you can rotate at any time.

  • Palo Alto EDL
  • FortiGate
  • Check Point
  • Cisco Firepower
  • SonicWall
  • pfSense
  • OPNsense

Endpoint & XDR

Push a URL or domain indicator so the endpoint agent blocks it on every device, including the ones that are off the corporate network.

  • Microsoft Defender for Endpoint
  • CrowdStrike Falcon
  • SentinelOne
  • Sophos Central
  • Trend Vision One

Email gateways

Block the sender for the whole tenant, quarantine or junk what they already sent, or hand the message to your gateway’s auto-pull.

  • Microsoft 365
  • Mimecast
  • Proofpoint TRAP
  • Check Point Harmony Email
  • Cisco Email Threat Defense
  • Barracuda
  • FortiMail

Identity

Sign the affected user out everywhere, require a password change at next sign-in, and flag the account as compromised for your conditional-access policies.

  • Microsoft Entra ID
  • Okta
  • Google Workspace

Collaboration & on-call

An incident card with the verdict, the user and one-click Confirm and Dismiss links, or a page to whoever is on call.

  • Slack
  • Microsoft Teams
  • PagerDuty
  • Opsgenie

SIEM, SOAR & ticketing

A pull API with cursor paging in native JSON, OCSF 1.1, Elastic Common Schema or CEF; signed webhooks that push each incident as it is recorded; playbooks for ServiceNow and Jira that close the loop.

  • Splunk
  • Microsoft Sentinel
  • Elastic
  • QRadar
  • ServiceNow
  • Jira
  • Any HTTPS endpoint

Directory & administrator access

Members and workspaces follow your directory groups. Console administrators are granted through an IdP group, with single sign-on enforced for them.

  • Microsoft 365 / Entra ID
  • Google Workspace

Deployment & MDM

Silent, zero-touch install of the browser extension with the device and user pre-registered, so nobody has to sign in.

  • Intune
  • Group Policy
  • Jamf
  • Kandji
  • Mosyle
  • Addigy
  • SimpleMDM
  • Chrome Enterprise
  • NinjaOne
  • ManageEngine
  • SOTI
  • Hexnode
  • Linux

Every connector is built on the vendor’s published API and tested with a connection check before it can be used. We validate the actions you enable in your own tenant during onboarding.

Bring your own threat intelligence

Browser Security ingests the feeds you already licence and blocks every URL in them, in every workspace of your organisation, on the schedule you choose.

Point SafeToOpen at a feed, pick the list group and the refresh interval, and test the parse before anything is blocked. New entries are blocked within minutes of publication; entries the vendor retires can be purged with the feed. Feed entries are never shared with SafeToOpen or with anyone else. They stay your intelligence.

  • MISP
  • TAXII 2.1
  • STIX 2.1 bundles

Automation you can switch on without holding your breath

Response actions are built for the analyst who has to answer for them the next morning.

Confirm or automaticEach rule fires when an analyst confirms the incident, or on its own above a minimum severity you set, for the incident kinds you name.
Dry-run firstNew rules record what they would have done without touching your tools, so you can read the log before going live.
UndoActions the vendor allows to be reversed can be rolled back from the incident, and the rollback is logged too.
Preview before you pressThe Respond panel shows exactly which targets each rule would act on for this incident, and what has already been done.
Least privilegeEvery connector lists the permissions it needs. Tokens are shown once, stored encrypted, and revoked in one click.
Audit trailWho triggered what, when, against which target, and the vendor’s response, exported to your SIEM with everything else.

How it fits your fleet

Questions, answered

Seconds. When SafeToOpen flags a page or an email, the incident appears in the console with the URL, sender and affected user already attached. An analyst confirms it once and every configured response action runs at the same time: the URL is blocked in your DNS filter, secure web gateway, endpoint protection and firewall list, the user is signed out and asked to reset their password, the sender is blocked in your mail gateway, and the on-call is paged. Rules can also run automatically for incidents above a severity you choose, with no analyst involved.

Network and web: Cisco Umbrella, Zscaler Internet Access, Netskope, Cloudflare Zero Trust, and a hosted blocklist that Palo Alto, FortiGate, Check Point, Cisco Firepower, SonicWall, pfSense and OPNsense pull directly. Endpoint: Microsoft Defender for Endpoint, CrowdStrike Falcon, SentinelOne, Sophos Central, Trend Vision One. Email: Microsoft 365, Mimecast, Proofpoint TRAP, Check Point Harmony Email, Cisco Email Threat Defense, Barracuda, FortiMail. Identity: Microsoft Entra ID, Okta, Google Workspace. Collaboration and on-call: Slack, Microsoft Teams, PagerDuty, Opsgenie. SIEM and ticketing: a pull API in JSON, OCSF, ECS or CEF, signed webhooks, ServiceNow and Jira.

Yes. Browser Security ingests URL and domain feeds from abuse.ch URLhaus and ThreatFox, OpenPhish, PhishTank, MISP, any TAXII 2.1 server or STIX 2.1 bundle, Recorded Future risk lists, Proofpoint ET Intelligence, and plain text, CSV or JSON lists from any vendor. Feeds refresh on a schedule from every 15 minutes to weekly, and every URL is blocked in each workspace of your organisation. Feed entries stay yours; they are never shared with SafeToOpen.

Each rule starts in dry-run mode, which records what would have happened without touching your tools. Rules fire on confirm by an analyst or automatically above a minimum severity. Actions that the vendor allows to be undone can be rolled back from the console, and every action is written to the audit trail with who triggered it and what the vendor returned. Connector secrets are encrypted at rest and each connector lists the exact permissions it needs.

Connectors, rules and feeds are configured per client organisation, so each client’s tools receive only that client’s incidents. Organisations can be linked so a URL confirmed in one client is blocked across every linked client at once, and the MSP overview shows open incidents, connector health and feed status for every client on one screen.
