Bingnote users trust us with billions of their notes, projects, and ideas. That trust is based upon us keeping that data both private and secure. The information on this page is intended to provide transparency about how we protect that data. We will continue to expand and update this information as we add new security capabilities and make security improvements to our products.

Security Program

Security is a dedicated team within Bingnote. Our security team's charter is protecting the data you store in our service. We drive a security program that includes the following focus areas: product security, infrastructure controls (physical and logical), policies, employee awareness, intrusion detection, and assessment activities.

The security team runs an in-house Incident Response (“IR”) program and provides guidance to Bingnote employees on how to report suspicious activity. Our IR team has procedures and tools in place to respond to security issues and continues to evaluate new technologies to improve our ability to detect attacks against our infrastructure, service, and employees.

We periodically assess our infrastructure and applications for vulnerabilities and remediate those that could impact the security of customer data. Our security team continually evaluates new tools to increase the coverage and depth of these assessments.

Network Security

Bingnote defines its network boundaries using a combination of load balancers, firewalls, and VPNs. We use these to control which services we expose to the Internet and to segment our production network from the rest of our computing infrastructure. We limit who has access to our production infrastructure based on business need and strongly authenticate that access.

Account Security

Bingnote never stores your password in plaintext. When we need to securely store your account password to authenticate you, we use PBKDF2 (Password Based Key Derivation Function 2) with a unique salt for each credential. We select the number of hashing iterations in a way that strikes a balance between user experience and password cracking complexity.

While we don’t require you to set a complex password, our password strength meter will encourage you to choose a strong one. We limit failed login attempts on both a per-account and per-IP-address basis to slow down password guessing attacks.

Bingnote offers two-step verification (“2SV”), also known as two-factor or multi-factor authentication, for all accounts. Our 2SV mechanism is based on a time-based one-time password algorithm (TOTP). All users can generate codes locally using an application on their mobile device or can choose to have the codes delivered as a text message.

Product Security

Securing our Internet-facing web service is critically important to protecting your data. Our security team drives an application security program to improve code security hygiene and periodically assess our service for common application security issues including: CSRF, injection attacks (XSS, SQLi), session management, URL redirection, and clickjacking.

Our web service authenticates all third party client applications using OAuth. OAuth provides a seamless way for you to connect a third party application to your account without needing to give the application your login credentials. Once you authenticate to Bingnote successfully, we return an authentication token to the client to authenticate your access from that point forward. This eliminates the need for a third party application to ever store your username and password on your device.

Every client application that talks to our service uses a well-defined thrift API for all actions. By brokering all communications through this API, we’re able to establish authorization checks as a foundational construct in the application architecture. There is no direct object access within the service and each client’s authentication token is checked upon each access to the service to ensure the client is authenticated and authorized to access a particular note or notebook. Customer Segregation

The Bingnote service is multi-tenant and does not segment your data from other users’ data. Your data may live on the same servers as another user’s data. We consider your data private and do not permit another user to access it unless you explicitly share it.

Media Disposal and Destruction

We securely erase or destroy all storage media if it has ever been used to store user data. We follow NIST’s guidance in special publication 800-88 to accomplish this. For an example of how we securely destroy broken hard drives, please check out this blog article.

We utilize a variety of storage options in Google’s Cloud Platform (“GCP”), including local disks, persistent disks, and Google Cloud Storage buckets. We take advantage of Google’s cryptographic erasure processes to ensure that repurposing storage does not result in exposing private customer data.

Activity Logging

The Bingnote service performs server-side logging of client interactions with our services. This includes web server access logging, as well as activity logging for actions taken through our API. We also collect event data from our client applications. You can view the recent access times and IP addresses for each application connected to your account in the Access History section of your Account Settings.

Transport Encryption

Bingnote uses industry standard encryption to protect your data in transit. This is commonly referred to as transport layer security (“TLS”) or secure socket layer (“SSL”) technology. In addition, we support HTTP Strict Transport Security (“HSTS”) for the Bingnote service . We support a mix of cipher suites and TLS protocols to provide a balance of strong encryption for browsers and clients that support it and backward compatibility for legacy clients that need it. We plan to continue improving our transport security posture to support our commitment to protecting your data.

We support STARTTLS for both inbound and outbound email. If your mail service provider supports TLS, your email will be encrypted in transit, both to and from the Bingnote service.

We protect all customer data flowing between our data center and the Google Cloud Platform using IPSEC with GCM-AES-128 encryption or TLS.

Encryption at Rest

In late 2016, we began migrating the Bingnote service to the Google Cloud Platform (“GCP”). Customer data that we store in GCP will be protected using Google’s built-in encryption-at-rest features. More technically, we use Google's server-side encryption feature with Google-managed encryption keys to encrypt all data at rest using AES-256, transparently and automatically. You can find additional information on how encryption at rest protects your data here.

Resiliency / Availability

We operate a fault tolerant architecture to ensure that Bingnote is there when you need it.

In our both our physical data centers and our cloud infrastructure, this includes:

  • Diverse and redundant Internet connections
  • Redundant network infrastructure including switches, routers, and firewalls
  • Redundant application load balancers
  • Redundant servers and virtual instances
  • Redundant underlying storage

Both Google and our colocation vendor provide fault tolerant facility services including: power, HVAC, and fire suppression.

We back up all customer content at least once daily. We do not utilize portable or removable media for backups.

Physical Security

We operate the Bingnote service using a combination of cloud services and physical data centers. 

For our data centers, we secure our infrastructure in a private, locked cage that includes 24x7x365 monitoring. Access to these data centers requires at a minimum, two-factors of authentication, but may include biometrics as a third factor. Each of our data centers has undergone a SOC-1 Type 2 audit, attesting to their ability to physically secure our infrastructure. Only Bingnote operations personnel and data center staff have physical access to this infrastructure and our operations team is alerted each time someone accesses our cage, including a video record of the event.

For our cloud services, we use the Google Cloud Platform. Google has undergone multiple certifications that attest to its ability to physically secure Bingnote’s data. You can read more about Google Cloud Platform’s security here.

All Bingnote data resides inside the United States.
