About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Zscaler (ZS) Post Q2 Earnings: Buy, Sell, or Hold?

ZS Cover Image

Zscaler currently trades at $206.71 and has been a dream stock for shareholders. It’s returned 355% since November 2019, blowing past the S&P 500’s 90.5% gain. The company has also beaten the index over the past six months as its stock price is up 16.8%.

Why Is Zscaler a Good Business?

After successfully selling all four of his previous cybersecurity companies, Jay Chaudhry's fifth venture, Zscaler (NASDAQ: ZS) offers software-as-a-service that helps companies securely connect to applications and networks in the cloud.

1. Skyrocketing Revenue Shows Strong Momentum

A company’s long-term sales performance signals its overall quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Thankfully, Zscaler’s 47.7% annualized revenue growth over the last three years was incredible. Its growth surpassed the average software company and shows its offerings resonate with customers.

2. ARR Surges as Recurring Revenue Flows In

Investors interested in Zscaler should track its annual recurring revenue (ARR) in addition to reported revenue. While reported revenue for a SaaS company can include low-margin items like implementation fees, ARR is a sum of the next 12 months of contracted revenue purely from software subscriptions, or the high-margin, predictable revenue streams that make SaaS businesses so valuable.

Zscaler’s ARR punched in at $2.45 billion in Q2, and over the last four quarters, its growth averaged 33.4% year-on-year increases. This performance was fantastic and shows that customers are willing to take multi-year bets on the company’s technology. Its growth also makes Zscaler a more predictable business, a tailwind for its valuation as investors typically prefer businesses with recurring revenue.

3. Operating Margin Rising, Profits Up

While many software businesses point investors to their adjusted operating margin, which excludes stock-based compensation (SBC), we prefer GAAP reporting because SBC is a legitimate expense used to attract and retain engineering and sales talent. This metric is a key measure of profitability reflecting a company's earnings before taxes and interest on debt.

Over the last year, Zscaler’s expanding sales gave it operating leverage as its margin rose by 8.9 percentage points. Although its operating margin for the trailing 12 months was negative 5.6%, we’re confident it can one day reach sustainable profitability.

Final Judgment

These are just a few reasons why we're bullish on Zscaler, and with its shares topping the market in recent months, the stock trades at 11.7x forward price-to-sales (or $206.71 per share). Is now a good time to buy? See for yourself in our in-depth research report, it’s free.
