Key Points Interested in Global X Cybersecurity ETF? Here are five stocks we like better. Cybersecurity ETFs may look similar at first glance, but their portfolio construction can lead to very different results. Global X Cybersecurity ETF, iShares Cybersecurity and Tech ETF and WisdomTree Cybersecurity Fund each take a distinct approach to the sector. For investors, the key differences come down to liquidity, diversification and how aggressively each fund targets growth. The AI rally has gone through several iterations, and the latest is the hardware-to-software rotation. AI’s threat to major software providers was likely always overblown, but it’s never been more apparent in the cybersecurity space. Cybersecurity stocks have soared lately as AI agents pose a growing cyber threat, and many companies now treat cybersecurity spending as a non-discretionary budget item. Cybersecurity ETFs may look interchangeable at first glance, but their performance can diverge meaningfully. The reason isn’t a few basis points of fees—it’s how each portfolio is built. For investors choosing between funds in this space, composition matters far more than the label on the package. ? Datavault AI Locks Down CyberCatch in $94M Security Rollup Breaking Down 3 Cybersecurity ETFs by Fund Construction Each of these ETFs is among the cheapest cybersecurity-themed options, with expense ratios ranging from 0.45% to 0.50%. Five basis points of fees may add up over decades, but it’s typically a rounding error for an investor buying thematic ETFs that aren’t meant to be held for a lifetime. Instead, composition matters, and each fund takes a different approach to the industry. At this scale, there’s no “best” ETF; there’s only personal preference and risk tolerance. Global X Cybersecurity ETF: The Choice for Liquidity The Global X Cybersecurity ETF (NASDAQ: BUG) is the largest fund on our list with more than $1.51 billion in assets under management (AUM) and more than 1 million shares traded daily on average. The fund tracks the Indxx Cybersecurity Index, a global index that uses a modified market-cap system and screens companies with at least 50% cybersecurity-related revenue. While each holding is cap-weighted with a limit preventing single-name exposure, the top 10 represent more than 60% of assets. The fund holds 34 positions, with 85% in the U.S., but it is the most top-heavy of the three ETFs with core holdings in large caps like Palo Alto Networks Inc. (NASDAQ: PANW) and CrowdStrike Holdings Inc. (NASDAQ: CRWD). Story Continues ? Home Depot Analysts See a Path to $375 and Beyond BUG also has the highest expense ratio at 0.50%, but its cheap spreads erase this five-basis-point gap. The median 30-day bid/ask spread is just 0.08%, making it the cheapest fund on our list to trade, which is important for active investors moving large blocks. BUG is an ideal vehicle for those who want an affordable and liquid pure play on the cybersecurity trade that also includes mid- and small-cap stocks. iShares Cybersecurity and Tech ETF: The Choice for Balance The iShares Cybersecurity and Tech ETF (NYSEARCA: IHAK) adds an industrials component to the portfolio, and its unique mix of holdings offers diversification away from typical cybersecurity funds. IHAK has $1.08 billion in AUM, trades about 180,000 shares daily on average, and has a median 30-day bid/ask spread of 0.17%. While it’s smaller and less liquid than BUG, it’s more balanced because of its international holdings and diversification away from the tech sector. ? Tesla’s Cybercab Launch Could Reshape Margins for Uber and Lyft The fund holds 51 different stocks, and follows the same rule of 50% revenue from cybersecurity activities. The top 10 holdings represent just 45% of assets, and more than 20% of these come from stocks residing outside the U.S. Companies like Qualys Inc. (NASDAQ: QLYS) and Netskope Inc. (NASDAQ: NTSK) are represented in the top five, and non-tech firms like Booz Allen Hamilton Holding Corp. (NASDAQ: BAH) are also in the top 20. IHAK is a great option for investors who want a balanced cybersecurity portfolio. The fund is diversified across countries and industries, has low volatility, and has mid-pack fees. WisdomTree Cybersecurity Fund: The Choice for Conviction Finally, the WisdomTree Cybersecurity Fund (NASDAQ: WCBR) has the smallest AUM and the highest risk. It may also have the most upside because of its unique filter. The fund tracks an index with a revenue-growth filter; constituent companies must derive 50% of revenue from cybersecurity activities and have grown revenue 7% over a trailing three-year period. This additional growth screen explains why WCBR has outperformed BUG and IHAK so far in 2026. By screening for growth and focusing 100% on information technology, WCBR has the highest beta of the three ETFs at 0.97, which also means the lowest margin of safety. The fund holds just 33 stocks and has a mere $133 million in AUM, so the 0.45% expense ratio is often negated by the 0.23% median 30-day bid/ask spread. WCBR is the riskiest of the three, but it also gives significant portfolio weight to growing upstarts like Rubrik Inc. (NYSE: RBRK) alongside megacap giants like Palo Alto. The growth screen helps capture maximum upside, but it also offers the least protection against drawdowns.
