          <h3>The Challenge</h3>
          <span class='sub-heading'>Securing service-to-service communication with firewalls doesn’t scale in dynamic settings.</span>
          <div id='segmentation-challenge-animation' class='g-animation-block'>
            <%= inline_svg 'consul-connect/svgs/segmentation-challenge.svg' %>
          </div>
          <p>East-west firewalls use IP-based rules to secure ingress and
            egress traffic. But in a dynamic world where services move across
            machines and machines are frequently created and destroyed, this
            perimeter-based approach is difficult to scale as it results in
            complex network topologies and a sprawl of short-lived
            firewall rules.</p>
        </div>
        <div>
          <span class='dot'></span>
          <h3>The Solution</h3>
          <span class='sub-heading'>Service segmentation for dynamic service authorization.</span>
          <div id='segmentation-solution-animation' class='g-animation-block'>
            <%= inline_svg 'consul-connect/svgs/segmentation-solution.svg' %>
          </div>
          <p>Service segmentation is a new approach to secure the service itself
            rather than relying on the network. Consul uses service policies to
            codify which services are allowed to communicate. These policies
            scale across datacenters and large fleets without IP-based rules or
            networking middleware.</p>

            <p>TLS certificates are used to identify services and secure communications. Certificates use the SPIFFE format for interoperability with other platforms. Consul can be a certificate authority to simplify deployment, or integrate with external signing authorities like Vault.</p>
