PCI DSS Level 1 Certification

SiteLink takes data safety seriously and spares no expense to maintain PCI DSS Level I and SSAE 16 (SOC I) Type II certification – the highest standard of software and server security certification available. SiteLink also hires outside penetration test companies, subscribes to security services, continually assesses threat levels and updates security methods.

The Payment Card Industry (PCI) Data Security Standard (DSS) is an information security standard defined by the Payment Card Industry Security Standards Council. These standards cover all aspects of cardholder data in a system and include card data entry, processing and secure payment applications.

Each year SiteLink undergoes a rigorous PCI DSS Level 1 certification audit and independent 3rd party penetration tests. Leading brands such as American Express, Discover, MasterCard and Visa require PCI DSS for their data security compliance programs.

PCI DSS Level 1 Certification brings peace of mind to owners with the understanding that external auditors have certified the SiteLink suite of software products after the most stringent security audit.

Status Monitoring

Remarkably, SiteLink data center servers have been maintained without unscheduled downtime since Web Edition’s debut in April 2006.

    • Uptime status. Customers can be confident that their data is accessible nearly 24/7. Occasionally, situations outside of SiteLink’s control arise that may impact services, such as regional outages or ISP routing issues. When these do occur, it’s easy for a customer to quickly check the SiteLink status webpage to see if any problems have been reported in their area and when it will be resolved. Customers can also subscribe to convenient, customizable status page updates to instantly be notified of any or all alerts.

      The screenshot below is an example of the SiteLink status page where all services are listed as operational.

    • Response times. The status page also includes visual representations of SiteLink server response times - which is the amount of time it takes for a web server to respond to a request from a client. Response times for SiteLink Logon Web Service, Transaction Web Service, Transaction API, Reporting API, myHub and Web Template are all shown on the SiteLink status page. Examples are shown below:

Tier 4 Data Center

The SiteLink servers are located in Tier 4 data centers - the highest data center rating available.Tier 4 data centers provide 99.995% uptime per year along with 2N+1 fully redundant infrastructure (the main difference between tier 3 and tier 4 data centers), 96 hour power outage protection and 26.3 minutes of annual downtime.

SiteLink utilizes a global leader for its Web Application Firewall (WAF), Content Delivery Network (CDN), Distributed Denial of Service Protection (DDoS) and Load Balancing Provider. All SiteLink traffic must pass through this provider and be inspected before being allowed to be redirected to the SiteLink infrastructure. Additional features include 9 Internet Service Providers; ITAR, EU-US Privacy, SOC 1, SOC 2, HIPAA, GLBA and PCI Colocation; and a hurricane-proof and ballistics-resistant building.

    • 2N fully redundant power delivery. Each component in a Tier 4 data center is redundant all the way to the utility power. Each piece of SiteLink equipment plugs into two separate power distribution Units (PDUs) which then connect to separate power panels. The power panels connect to separate uninterruptible power supplies (UPSs) which then connect to separate automatic transfer switches. These connect to separate generators and utility power substations.

    • Enterprise cloud logging. Every action in the SiteLink infrastructure is logged in real time to our enterprise cloud logging provider, indexed and evaluated for threats. All logs are retained for a minimum 365 days. This includes every networking connection in/out of the cabinet, server access, configuration change, etc.
    • Exterior firewall protection. The exterior level firewalls evaluate all traffic entering or leaving the SiteLink cabinet and blocks all traffic that doesn’t pass inspection.
    • Threat management devices. The threat management devices inspect every piece of data that enters or leaves the SiteLink infrastructure in realtime to determine if the data is safe or not. This is monitored 24/7 by an external security provider. These devices can immediately stop a threat as soon as it’s detected and prevent any malicious content into the environment and prevent any secured data from being taken.
    • Interior firewall protection. The interior level firewalls evaluate all traffic between the Web Servers and the Database Servers. Only secured traffic that originates from our secured web servers is allowed to access data in the SiteLink databases.
    • Database servers. The database servers host their databases on fully redundant solid-state hard drive arrays.
    • Backups. SiteLink’s impressive backup systems begin with the following:
      • SiteLink Customer PC
      • SiteLink Database Server
      • Redundant solid-state hard drive arrays (replicate between arrays every 5 minutes)
      • Log shipping server (replicate every 10 minutes)
      • Fully encrypted SQL database backups
        • Backup Server
        • Historical hard-drive array (60 days of full SQL backups)
        • Amazon S3 (full SQL backups kept in perpetuity)

Restoring your data on any computer after a crash or accessing data from any PC or mobile device only requires Internet access and your SiteLink login credentials.

Data Confidence

SiteLink sets the gold standard for data security in self-storage: critical data is encrypted and only transmitted through secure channels, snapshots of all data are taken and stored every 5 minutes, and backups are stored in multiple locations–on and off-site. You can rely on SiteLink to keep your data secure, and with this peace of mind you can focus on running your self-storage business.
