With the rise of IP telephony and hosted solutions (Centrex), cyber-attacks targeting these infrastructures are multiplying. Many partners underestimate these risks and fail to implement adequate security measures. The result: costly intrusions, phone fraud and service interruptions.
Find out more about the most common threats, the essential best practices for securing your infrastructure, and the solutions offered by Sewan.
The main threats to hosted and trunk telephony
In concrete terms, VoIP systems can face a number of different types of hacking:
- Toll fraud: Hackers take control of a SIP account to make calls to premium rate or international numbers, from which they profit.
- Takeover of user/telephone exchange accounts: Poorly protected SIP accounts can be compromised and used for malicious purposes (eavesdropping on conversations, stealing sensitive information, etc.).
🛡️Comment to protect against this?
- Use complex, unique passwords.
- Restrict calls to certain destinations (Europe only).
- Set up alerts for unusual call volumes.
- Deactivate inactive accounts.
- Enable strong authentication (2FA) where possible.
- Perform regular security audits.
- Set up ACLs (Access Control Lists).
Cyber attacks can have disastrous consequences not only for a company's operations, but also for its reputation and credibility with customers and partners. For Sewan, ensuring the cybersecurity of its partners is a crucial issue!
Sewan, security first!
To protect our partners and your customers from hacking, Sewan has set up a monitoring and alert system that detects unusual and fraudulent use of your telephony.
✅ Automatic detection and protection against piracy: an advanced algorithm manages maximum daily and monthly consumption limits, the number of outgoing channels, and analyzes multiple parameters (destination zone, time period, user profile) to prevent any attempt at fraud.
✅ Real-time monitoring of active calls: offers an instant commercial overview of calls in progress, providing an accurate view of current consumption.
✅ Outgoing call security: ability to restrict outgoing calls to specific IPs with strict security rules.
✅ Outgoing call volume control: quick and instantaneous set-up of limitations on the number of calls to premium destinations according to a daily range or based on a daily and monthly amount*.
✅ Outgoing call restriction: creation of black lists to block certain numbers, categories of numbers (e.g. premium rate) or specific destinations*.
As you can see, Sewan does everything in its power to prevent cyber-attacks on its telephony solutions. Don't hesitate to contact us for more information.
