Most Leaks Start With a Helpful Paste

No one means to cause a breach. An engineer pastes an API key into a channel to unblock a teammate. Someone drops a customer's personal data into a ticket to move faster. SideNote coaches your people the instant sensitive data enters the text box, adding a human-layer control that works across every application, not just the browser.

The Costliest Breaches Begin With a Routine Message

Your team already inspects endpoints, networks, and files. The gap is the person who decides to share something they should not, in a chat window or a ticket where after-the-fact controls never see it in time. By the time a scanner catches a pasted credential, it is already sitting in a persistent, searchable log.

Chat: #eng-oncall
here is the fix, try hitting the API directly

Live Credential Exposure

A production API key in a persistent channel is a credential leak. Share access through your secrets manager instead of pasting it in chat.

A Control Between the Employee and the Send Button

Endpoint, network, and file controls act on data that is already in motion. SideNote acts on the decision. Our agent operates at the OS level on company-owned devices, recognizing sensitive data as it enters any text box and coaching the person before the data moves.

Interception at the Source

SideNote reads sensitive data the moment it is typed or pasted into a text box, while the message is still a draft. The credential, record, or secret is caught before it ever reaches a channel, ticket, or thread.

OS-Level Coverage, Every App

A lightweight agent on company devices, not a browser extension or a single-mailbox plugin. It works across email, chat, documents, tickets, and internal tools, so there is no application where sensitive data slips through unseen.

Complements Your DLP

DLP blocks and logs after the fact, which trains people to route around it. SideNote adds the human layer your stack is missing, coaching the person in the moment and reducing the incidents your team has to chase in the first place.

On-Premises & Privacy-Preserving

Edge agents on company devices work with a centralized engine on your infrastructure. Message content never leaves your network, and leadership sees only anonymized, aggregated data-handling trends.

It Reads Sensitive Data
the Way a Reviewer Would

Pattern matching alone floods your team with false positives and misses the leaks that matter. A string that looks like a key is not always a live credential, and a nine-digit number is not always an SSN. Context is what separates a real exposure from noise.

SideNote reasons about sensitive data the way an experienced reviewer would: it recognizes what the data is, weighs where it is about to go, and judges the exposure that creates. Then it coaches the person, in plain language, before the data leaves the text box.

Comprehensive Sensitive-Data Coverage

SideNote recognizes the categories of data that create real exposure when they land in the wrong place, from credentials and personal data to regulated records and confidential IP. Below are six areas where accidental exposure is most common; our model covers the full spectrum of sensitive data your people handle.

Where exposure happens most
01

Credentials & Secrets

Detect API keys, access tokens, passwords, and connection strings as they are pasted into chats, tickets, and documents, before a live credential lands in a persistent log.

02

Personal Data / PII

Recognize SSNs, dates of birth, and addresses in context, so a real identifier is coached while ordinary numbers pass without noise.

03

Payment Data / PCI

Catch card numbers and cardholder data before they are shared through channels that fall outside your PCI scope and controls.

04

Health Data / PHI

Flag HIPAA-regulated patient information as it is entered, keeping protected health data out of unmanaged communications.

05

Confidential & IP

Identify source code, trade secrets, and roadmaps leaving through channels where your organization loses control of them.

06

Regulated Transfers

Recognize data crossing channels or borders improperly, so a transfer that breaks policy or regulation is caught before it happens.

Data Protection in Three Steps

01

Deploy to Your Endpoints

Install the SideNote agent on company-owned devices. It operates at the OS level to cover every application, with optional plugins for Outlook, Gmail, Slack, and Teams that enable deeper protection like outbox holds and full-context analysis, with no workflow disruption.

02

Monitor in Real Time

As employees type and paste across any channel, SideNote recognizes sensitive data in context. When a real exposure is forming, the person receives immediate coaching that explains the risk and points to the safe path, all before the data leaves the text box.

03

Coach & Prevent

Employees learn why a credential, record, or secret creates exposure and how to share it safely, through the vault or an approved channel. Over time, repeat incidents drop and your organization builds genuine data-handling habits.

Built for Security and Privacy Leaders

SideNote adds the layer your stack is missing: real-time coaching at the point of decision, across every application, with the content kept private and the reporting kept aggregate.

Catch Secrets at the Source

Recognizes API keys, tokens, passwords, and personal data as they are typed or pasted, catching the exposure while the message is still a draft.

OS-Level, Every App

A single lightweight agent covers email, chat, documents, tickets, and internal tools, so there is no application where sensitive data slips through unseen.

Complements DLP

Your DLP blocks and logs. SideNote adds the human layer, coaching the person in the moment so fewer incidents reach the queue at all.

Education, Not Surveillance

Every alert teaches employees why the data creates exposure and how to share it safely. Good data-handling habits compound across your organization.

Privacy-Preserving by Design

Message content never leaves your network. Leadership sees anonymized, aggregated data-handling trends, never the content of individual messages.

Enterprise Scale

Deployed across tens of thousands of endpoints with zero impact on productivity. Built from day one for Fortune 500 scale and security requirements.

Visibility for Leadership,
Privacy for Everyone

SideNote's dashboard gives security and privacy teams real-time visibility into data-handling risk across the organization, without ever exposing the content of individual messages.

  • Exposure trends by team, so you can see where risk concentrates
  • Anonymized hotspots to target awareness where it is needed most
  • Complements DLP with human-layer coaching, not another block-and-log feed
  • Privacy-preserving reporting: aggregate signals, never message content
