Network Security API C++ Client Library

An idiomatic C++ client library for the Network Security API, a cloud first service that helps you secure egress web traffic (HTTP/S).

While this library is GA, please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.


The following shows the code that you'll run in the google/cloud/networksecurity/quickstart/ directory, which should give you a taste of the Network Security API C++ client library API.

#include "google/cloud/networksecurity/v1/network_security_client.h"
#include "google/cloud/project.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 2) {
    std::cerr << "Usage: " << argv[0] << " project-id\n";
    return 1;

  namespace networksecurity = ::google::cloud::networksecurity_v1;
  auto client = networksecurity::NetworkSecurityClient(

  auto const parent = std::string{"projects/"} + argv[1] + "/locations/-";
  for (auto r : client.ListAuthorizationPolicies(parent)) {
    if (!r) throw std::move(r).status();
    std::cout << r->DebugString() << "\n";

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;

Main classes

The main class in this library is networksecurity_v1::NetworkSecurityClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock networksecurity_v1::NetworkSecurityClient when testing your application.
