Notify Norwalk is a service provided by Emergency Communication Network (ECN). This company takes security and privacy concerns very seriously and does not sell, trade, lease, or loan any data about our clients to any third party. From a technical perspective, we utilize multiple physical and virtual layers of firewalls to maintain data security. ECN only utilizes secure transmissions with its customers. No confidential information is ever transmitted between ECN and its customers using e-mail or FTP, but rather always utilizes either a VPN tunnel or SSL. Data is hosted in state-of-the-art facilities which require photo identification, thumb-print recognition, keyed access, and are manned 24 hours a day, seven days a week with full-security personnel. All data is encrypted prior to being placed on tape for offsite storage. ECN also retains an external, independent security firm to perform annual security audits.
