How secure is online and cloud accounting software?

Reputable cloud accounting platforms use AES-256 encryption for data at rest and TLS 1.2 or higher for data in transit. This is the same standard used by banks and is effectively uncrackable with current technology. Note.now uses AES-256 encryption for all stored financial data.

Encryption at rest means your data is encrypted on the server - even if someone physically accessed the storage hardware, the data would be unreadable without the encryption keys. Encryption in transit means the connection between your browser and the server is encrypted, so traffic cannot be intercepted. Both layers together provide defence in depth against the most common attack vectors.

Enable two-factor authentication (2FA) on your accounting account. This means even if someone gets your password, they cannot log in without a code from your phone. Note.now supports 2FA for all accounts and recommends enabling it as the first step after signing up.

Password breaches are far more common than most people realise. If you reuse passwords across services, and one of those services is breached, attackers will try your credentials on financial accounts. 2FA stops this attack completely - without physical access to your phone, the password alone is not enough. This single step is the highest-impact security action you can take.

Cloud platforms automatically back up your data daily - often with point-in-time recovery options. This is a significant advantage over local software where a hard drive failure can mean losing years of financial records. Note.now maintains daily backups with a 99.9% uptime SLA.

Point-in-time recovery is particularly valuable. If an error is made today and you do not notice for two weeks, you can restore a snapshot from before the error was introduced. This is not possible with a simple daily backup that overwrites the previous version. Ask any cloud provider specifically whether they offer point-in-time recovery and for how far back.

Good accounting software lets you control who sees what. Give your bookkeeper access to transactions but not payroll. Give your accountant read-only access to reports. Note.now has granular role-based permissions so you can invite team members without exposing sensitive data.

The principle of least privilege - giving each person only the access they need for their job - reduces the risk of both accidental errors and deliberate fraud. A bookkeeper who can only categorize transactions and cannot approve payments cannot be the source of an unauthorized transfer. Separating duties is a fundamental internal control that your accounting software should make easy to enforce.
