U.S.-listed examples include BUG, CIBR, HACK, and IHAK. They use different indexes and have different holdings and costs, so compare each fund’s current documents before investing. A basket spreads company-specific exposure, but a cybersecurity ETF is still a concentrated sector investment—not a substitute for broad diversification.
How a cybersecurity ETF works
An ETF holds a portfolio of securities and trades on an exchange. A cybersecurity ETF typically follows an index whose rules determine which companies qualify and how the fund weights them. That gives you exposure to multiple businesses connected to cybersecurity, but the fund’s holdings may include companies with substantial businesses outside cybersecurity.

What to compare before choosing a fund
Index rules and holdings
Each benchmark defines cybersecurity exposure differently, which can produce different portfolios. Review the index methodology and the fund’s full, current holdings—not only the number of companies. Pay particular attention to the largest positions, their weights, and how much of each company’s business is actually cybersecurity-related.
#1 Best Overall
Fund and trading costs
The expense ratio is an ongoing fund cost, not the only cost of ownership. Also check brokerage charges, the bid/ask spread, and whether shares are trading at a premium or discount to net asset value. These can affect your results. Turnover can also help explain how frequently a portfolio changes, though it does not by itself tell you whether a fund is better suited to you.
Geography and portfolio role
Check whether the fund’s exposure is primarily U.S.-focused or global, and how its index weights and rebalances constituents. Consider whether a narrow sector fund belongs as a limited allocation alongside diversified broad-market holdings rather than replacing them. The appropriate allocation depends on your circumstances, including your goals, time horizon, existing portfolio, and risk tolerance.
Understand the risks
- Sector concentration: A fund may hold many companies yet remain exposed to one industry. Holdings can move together when technology or growth stocks fall. Amplify warns that narrowly focused investments typically exhibit higher volatility. Amplify HACK fund page
- Loss of principal: ETF share prices can decline, and you can lose money. Owning a basket reduces dependence on a single company, but it does not remove equity-market risk.
- Trading differences: ETF shares trade at market prices that can differ from net asset value. Spreads and brokerage charges affect the price you pay or receive.
- Tracking and performance: An index is not directly investable, and index returns usually do not include a fund’s expenses. A fund’s returns can differ from its benchmark.
How to use performance information
Historical returns are meaningful only with their measurement date, period, fee treatment, and benchmark. For example, First Trust reported CIBR net asset value total returns of 40.36% year to date and 37.44% over one year through August 31, 2026. First Trust cautions that past performance does not guarantee future results and that actual investor returns may differ. Those figures describe a past period; they are not a forecast or a stand-alone basis for selecting a fund. First Trust CIBR fund page

- Confirm availability: Check whether your broker offers the ETF and whether it is available to investors in your country.
- Read current fund documents: Review the statutory prospectus, index description, holdings, fees, and risk disclosures on the fund issuer’s site.
- Check the trade: Review the current bid/ask spread, any premium or discount to net asset value, and your broker’s charges before placing an order.
- Consider your wider finances: Decide whether a sector-focused holding fits alongside your diversified investments and financial plan. Tax treatment and investor protections vary by jurisdiction.
